| OpenAI Custom GPTs Retirement Masterclass Part 2: Essential Survival Guide for Creators & Developers. Learn step-by-step how to secure your system instructions, protect your intellectual property, and migrate your GPTs safely before the December 2026 deadline. Read the full guide now. |
If you built a Custom GPT, the actual asset was never the GPT itself. It was the instructions, the reference files, and the specific way you solved a problem for your audience. OpenAI is retiring the container that housed that work. The work itself is still yours to carry forward, if you handle the next few weeks correctly.
Part 1 covered the official retirement timeline. This part is written specifically for creators and sellers: what to actually do right now, how migration works in practice, and an honest look at the monetization question most creators are quietly worried about.
First: Why Panic Is the Wrong Response Here
Before anything else, it's worth saying clearly: nothing about this retirement happens instantly, and nothing you built disappears the moment you read this article. Custom GPTs remain fully usable until their actual retirement date, December 11, 2026 for most accounts, or February 11, 2027 for Enterprise workspaces with an approved deferral. That's real time to work with, not a countdown measured in days.
The creators who end up in genuine trouble here are almost always the ones who wait until the final week to start. The ones who come through this cleanly are the ones treating it as a structured migration project with a deadline, not an emergency.
Step One: Take Inventory Before You Touch Anything
The single most important action right now has nothing to do with OpenAI's migration tool. It's making sure the actual intellectual property behind your GPT exists somewhere you fully control, independent of ChatGPT entirely.
What to Save, Specifically
Open each GPT you've built and copy out its full system instructions into a separate document, word for word. Download every reference file and knowledge document you uploaded to it. Note which external apps or custom actions it connects to, and how each one is configured. Save a handful of your own test conversations or prompts, specific examples you'd use to confirm a migrated version still behaves correctly.
This step alone, done properly, means you could theoretically rebuild your GPT's core logic in any tool, OpenAI's plugin system or otherwise, even if migration goes wrong or a deadline gets missed. Treat this as backing up the actual business asset, not a formality.
Step Two: Understand What Migration Actually Preserves (and What It Doesn't)
OpenAI's migration tool is genuinely useful, but it's worth knowing its exact boundaries before relying on it completely.
What Transfers Automatically
When you migrate a GPT, its instructions become what OpenAI calls a "skill" inside a new plugin, and any connected apps carry over as part of that plugin. The migration uses your GPT's latest published version specifically, not unpublished drafts sitting in the editor.
What Does Not Transfer
| Element | What Happens |
|---|---|
| Unpublished drafts | Must be published before migrating, or the changes are lost |
| Conversation history | Does not carry over to the new plugin at all |
| Custom actions (API connections) | Must be manually rebuilt; no automatic transfer |
| Selected model configuration | Does not carry over automatically |
Custom actions deserve particular attention if your GPT relied on them. If your GPT calls an external API, a booking system, a database lookup, a third-party service, that connection needs to be manually reconstructed in the new plugin format. Budget real time for this specifically, since it's the step most likely to be underestimated.
How to Actually Start Migration
Once migration is available for your account, go to My GPTs and select Migrate to plugin for the specific GPT you want to move. Review the migration details OpenAI presents, then follow the prompts to complete it. After migrating, the original GPT becomes read-only, meaning it still exists and functions until its retirement date, but you can no longer edit it, only the new plugin going forward.

Step Three: Test Before You Trust
Once a GPT has been migrated, don't assume it works identically just because the process completed without an error message.
Run the same handful of test prompts you saved during your inventory step and compare the results directly against how the original GPT used to respond. Check specifically whether any connected apps or custom actions you rebuilt are firing correctly, since a silent failure here is easy to miss until a user hits it. Confirm the underlying model setting matches what the GPT originally used, since this doesn't carry over automatically and can meaningfully change output quality and behavior if left on a default.
A migrated plugin starts private by default. Migration does not automatically publish it or make it available to anyone who previously had access to your GPT, so if you're running this as a service for others, re-sharing or re-publishing is a deliberate step you still need to take yourself.
The Monetization Question: An Honest Look
This is the part of the conversation creators are least likely to get a straight answer on elsewhere, so it's worth addressing directly.
What OpenAI Originally Promised
Back in January 2024, when the GPT Store launched, OpenAI announced plans for a builder revenue program, paying creators based on user engagement with their GPTs, with US builders eligible first. Some creators report being part of a small, limited early test of this payment system at the time.
What's Actually Confirmed as of Late 2026
As of this writing, there is no current, publicly documented OpenAI page describing an active, ongoing builder revenue program available broadly to creators. The help page that used to address GPT monetization now redirects to a general article about sharing and publishing GPTs, with no payment details included. If you built a GPT specifically expecting ongoing engagement-based payouts, it's worth treating that expectation with real caution rather than assuming it's quietly still running in the background.
If You've Been Selling GPT Access Directly
Some creators sell access to a Custom GPT directly, outside the official GPT Store, through their own website or a paid community. If that's your situation, the retirement timeline is a direct business continuity issue, not just a platform inconvenience. Customers who paid for ongoing access deserve a clear, proactive update from you about what's changing and when, well before December 11 arrives, rather than discovering it themselves when the product suddenly stops working.
A Practical Migration Checklist
Work through this in order, rather than jumping straight to the migration tool:
- Export and save every GPT's full instructions, reference files, and a record of its connected actions.
- Publish any unpublished draft changes now, since drafts don't carry into migration.
- Migrate each GPT individually through My GPTs, reviewing the details OpenAI presents at each step.
- Manually rebuild any custom actions or API connections that don't transfer automatically.
- Test the migrated plugin against your saved examples before telling anyone it's ready.
- If you sell access to a GPT, notify your customers directly with a clear timeline, well ahead of the retirement date.
Frequently Asked Questions
Will I lose my GPT's conversation history during migration?
Yes. Conversation history does not transfer to the new plugin under OpenAI's current migration process. If specific past conversations matter to you, save or export them separately before the GPT reaches its retirement date.
Can someone else migrate my GPT for me?
In personal accounts, the GPT's creator is the one who migrates it. In Enterprise workspaces, either the GPT's creator or a workspace admin can perform the migration, depending on how the organization has configured permissions.
Am I still owed payment for a GPT that previously earned revenue?
This depends entirely on your specific arrangement with OpenAI and isn't something a general guide can answer for your account. If you were part of an early builder payment arrangement, check your account's billing and payment history directly, or contact OpenAI support for clarification specific to your situation.
What happens if I don't migrate before December 11, 2026?
The GPT and its public page become inaccessible once it reaches its retirement date. Migrating beforehand, or at minimum saving your instructions and files independently, is the only way to ensure continuity past that date.
Do I need to make my migrated plugin public again after migrating?
No, not automatically. A migrated plugin starts private by default, so if your GPT was previously public or shared with others, re-publishing or re-sharing is a separate, deliberate step you'll need to take after confirming the migration works correctly.
