What OpenAI says

In the guide for moving GPT workflows to plugins, OpenAI lists previous chats among the things that may not copy. Conversation starters may also not copy one-to-one.

What to save yourself

How

Copy important conversations into documents or notes, with the date and what they were about. We do not know of an official bulk export for a single GPT's chats, so check your account's data export options.

Use history as a test set

Your best past questions are the best way to verify the new version: testing guide. See the full transfer breakdown.
