An owner moves from ChatGPT to Claude. The new assistant knows the company biography but uses an old price, misses the current client rule, and repeats a correction settled last month. The biography moved. The operating record did not. Switch models by moving canonical facts, decisions, procedures, corrections, and open work into records you control. Give both models the same reading order and acceptance fixture. Compare business decisions, not prose style. ## Portable business context is not portable chat Chat history contains useful evidence. It also contains abandoned ideas, superseded instructions, model claims, jokes, and missing attachments. A generated summary compresses that mixed record. It may preserve preferences while dropping who approved a price or which correction superseded an older rule. Product guides such as [Plurality's context-transfer overview](https://plurality.network/blogs/universal-ai-context-to-switch-ai-tools/) describe ways to move context. Treat these as transport options, not evidence that transferred facts are authoritative. Persistent business context needs source roles, ownership, and correction history. The guide to [persistent context across AI tools](/articles/persistent-context-across-ai-tools) provides that foundation. For the specific ChatGPT-to-Claude route, follow the [reviewed memory import procedure](/articles/move-chatgpt-memory-to-claude) while preserving the same owned business packet. ## Move canonical records first Create a small set of maintained files for the job: - current facts with source and review date; - accepted decisions with owner and effective date; - procedure or task brief; - approved examples labeled for their role; - correction log with retest state; - open work with status, evidence, and next action; - exclusions and prohibited sources. Do not ask the old model to decide by itself what is canonical. Use the export and chats as evidence. A person or approved deterministic rule promotes records into current files. [Plain-text AI memory](/articles/plain-text-ai-memory) makes the set inspectable across vendors, editors, and ordinary file tools. ## Give the new model a context manifest The context manifest tells the runtime what to read and in what order. ```text job:: prepare weekly account brief business_id:: ACME-OPS required_sources:: decisions.md, account-context.md, corrections.md, open-work.md source_order:: decisions.md > corrections.md > account-context.md > open-work.md format_only:: accepted-example.md prohibited_sources:: archive/, raw-chat/ output:: drafts/weekly-account-brief.md acceptance:: current price, open blocker, next approved action, source citations stopping_point:: draft and receipt only ``` Keep vendor-specific message roles, tool schemas, and model names in an adapter. Keep business rules in the manifest and brief. This separation lets you diagnose failure. If both models choose an old price, inspect the records. If one ignores the source order, inspect that adapter and model behavior. ## Preserve project and client boundaries Do not combine every business, role, and client into one migration packet. Give each job a stable business or client identifier. Resolve that identifier before retrieval. Limit sources and output paths to the active scope. Record excluded data. A model switch is not permission to upload all archives to a new provider. Apply current data agreements, retention rules, and provider approvals. Use synthetic canaries to test separation. Each client gets a distinctive harmless value. The wrong value must never appear in another client's run. ## Transfer open work with evidence Open work needs more than a task title. For each item, capture: - stable ID; - current status; - owner; - last accepted decision; - supporting source; - completed steps; - blocker; - next permitted action; - approval state; - due date if authoritative. Do not let the new model infer status from the last chat message. The message may describe a proposal rather than accepted work. The replacement pattern in [replace the model without rebuilding business memory](/articles/replace-the-model-keep-business-memory) keeps the runtime disposable and the record durable. ## Inspect `model-switch-acceptance.md` Build one test for a real recurring job: ```markdown # Model switch acceptance job:: weekly account brief fixture:: fixtures/account-017-2026-W34/ models:: current-model, replacement-model required_sources:: decisions.md, corrections.md, open-work.md expected_decision:: recommend the approved phase-two task only required_facts:: price=$1,200; blocker=client access; owner=USER-017 prohibited_source:: archive/2025-pricing.md must_not:: send message; invent deadline; read another client folder receipt:: sources read, conflicts, output hash, stopping state pass:: all required facts; expected decision; no prohibited source; draft only ``` Freeze the fixture before running either model. Otherwise a changing source packet makes the comparison meaningless. ## Run the same task on both models Use fresh sessions. Do not give the replacement the old chat thread. Run the current model through its adapter, then the replacement through its adapter. Capture each output and receipt. Compare: 1. Did each model read every required source? 2. Did either read a prohibited source? 3. Did each identify the current authoritative decision? 4. Did either invent a fact or deadline? 5. Did each preserve the client boundary? 6. Did each stop at draft-only? 7. Can a reviewer trace claims to source records? 8. How much review and correction did each need? The outputs can use different words. Pass criteria should focus on facts, decision, boundary, and proof. ## Test corrections and conflicts Add one known correction to the fixture. For example, an older record says `$900` and the accepted decision says `$1,200` effective on a named date. Both models must use the accepted value and cite the governing record. Then add two equal-authority current sources that conflict. Both should stop and report the conflict. This test reveals whether the migration moved authority or only content volume. ## Compare tool access separately from reasoning The replacement model may pass a file-based fixture and still fail the live job because its adapter cannot reach the approved source or write the required draft path. Inventory each tool call by purpose, account, permission, and expected read-back. Test retrieval with a synthetic record before connecting live client systems. Keep external-action credentials disabled during the comparison. When one provider exposes a native feature that the replacement lacks, decide whether to reproduce the capability, change the job, or keep that step manual. Do not hide the missing capability inside a larger prompt. Record adapter failures separately from model decision failures. A missing connector, truncated file, or incompatible schema needs an integration fix. An unsupported conclusion from correctly supplied sources needs a different correction and test. This separation also keeps vendor comparisons honest. The model should not receive blame for a source the adapter never delivered, and a working connector should not excuse a model that ignored current authority. ## Keep the model replaceable After the switch, do not let new decisions accumulate only inside the replacement vendor. Write accepted corrections back to the canonical record. Keep prompts or adapters versioned. Store run receipts outside the provider. Repeat the fixture after model, tool, retrieval, or source-order changes. Vendor export tools can still help with discovery and evidence. ContextSwitchAI, for example, describes local export and searchable context transfer. [ContextSwitchAI](https://contextswitchai.github.io/ContextSwitchAI/) Treat any transfer utility as a transport layer. Review its privacy behavior, output completeness, and authority labels before using it for business records. Store the accepted fixture beside the brief. Give it a version and rerun trigger. The trigger should include model updates, adapter changes, source-schema changes, and new external capabilities. A switch remains proven only for the tested job and configuration. ## Run the migration test list Before declaring the switch complete: 1. Canonical files exist outside both model providers. 2. The manifest names source order and prohibited paths. 3. Open work has owners, status, evidence, and next actions. 4. Client and business IDs are enforced before retrieval. 5. Both models run the same frozen fixture. 6. Both choose the current decision. 7. Both apply the accepted correction. 8. Both stop on an equal-authority conflict. 9. Neither reads another client's canary. 10. Neither performs an external action. 11. Receipts record sources and output hashes. 12. The replacement's review burden is accepted by the owner. Fail the switch if the new model only reproduces a biography or style profile. Those are context elements, not proof of an operable business job. ## Approval and stopping boundary An agent may inventory records, prepare a manifest, convert approved context into owned files, build a synthetic fixture, and compare draft outputs. It stops before uploading sensitive archives to a new provider, changing live model routing, revoking the old account, changing permissions, or accepting the replacement. The system owner approves those exact changes. The migration also stops when source authority, client identity, data terms, or acceptance criteria are unresolved. The agent reports the missing decision rather than filling the gap from model memory. ## Tools and discussions referenced - [Plurality: Universal AI context](https://plurality.network/blogs/universal-ai-context-to-switch-ai-tools/) - [ContextSwitchAI](https://contextswitchai.github.io/ContextSwitchAI/) - [Reddit: Switching AI platforms without losing history](https://www.reddit.com/r/AI_Agents/comments/1sib397/how_to_switch_between_ai_platforms_and_not_losing/) ## Questions about How to Switch AI Models Without Losing Business Context ### Switched from ChatGPT to Claude - good call, but I lost months of context. How are people handling this? Move canonical facts, decisions, procedures, corrections, and open work into records you control instead of treating the old chat history as the source of truth. Give both models the same context manifest and acceptance fixture, then compare the business decisions and stop behavior. ### What about everything I've already taught it? Review the old archive for confirmed records with provenance, then move only the current facts, decisions, corrections, procedures, and open obligations needed for the job. Keep superseded instructions and generated summaries as evidence rather than promoting them into the new model's governing context. ### Do people who use multiple AI tools just accept the context loss as the cost of doing business or is there actually a solution I'm missing? Use a model-independent source set and context manifest so each supported tool reads the same authoritative records and exclusions. Test one current fact, one superseded fact, one accepted correction, one client boundary, and one missing source before declaring the switch complete. ## Save the visual summary model-switch-acceptance.md | fixtures/account-017-2026-W34 | decisions.md | corrections.md | open-work.md | archive/2025-pricing.md [Download the PNG](/infographics/switch-ai-models-without-losing-context-1200x1500.png) ## Related: Ownership and Migration - [Replace the Model Without Rebuilding the Business Memory](/articles/replace-the-model-keep-business-memory) - [Chat History Title Best Practices: Name AI Work by Client, Decision, and Date](/articles/chat-history-title-best-practices-business-ai) - [Convert a ChatGPT Export to Markdown Without Making Every Chat Truth](/articles/chatgpt-export-to-markdown-business-memory) ---- ```text .|########||. .|########||. .|########||. |##||. .||##|. |##||. .||##|. |##||. .||##|. |#|. .|#|. |#|. .|#|. |#|. .|#|. |#| |#| |#| |#| |#| |#| .#| |#. .#| |#. .#| |#. .#. .#| .#. .#| .#. .#| |#. .#| |#. .#| |#. .#| |# ...... #| |# ...... #| |# ...... #| .# ||#########| #| .# ||#########| #| .# ||#########| #| .#. |######||######|. .#. .#. |######||######|. .#. .#. |######||######|. .#. #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# # .||####|###########################|. # # .||####|###########################|. # # .||####|###########################|. # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || #. .######|#|#########| .# #. .######|#|#########| .# #. .######|#|#########| .# .#. |#####||||#####| .#. .#. |#####||||#####| .#. .#. |#####||||#####| .#. |# ||########|| #. |# ||########|| #. |# ||########|| #. |# ...... #| |# ...... #| |# ...... #| |#. .#| |#. .#| |#. .#| |#. .#. |#. .#. |#. .#. .#| |#. .#| |#. .#| |#. |#| |#| |#| |#| |#| |#| .|#|. .|#|. .|#|. .|#|. .|#|. .|#|. |##||. .||##| |##||. .||##| |##||. .||##| .||########||. .||########||. .||########||.
