OpenAI’s migration FAQIf you created the GPT
Review the published version in My GPTs. When Migrate to plugin is available, use it, then test the replacement and check who can access it.
If you use someone else’s GPT
Check the GPT notice and the creator’s guidance for a replacement. Ask the creator about features you rely on before switching.
If you mostly reuse instructions and files
You can recreate the workflow in a ChatGPT Project with your own instructions and reference files. Review any Actions separately.
