Importing old chats here is a reference upload, not a full account migration. An export from an eligible account can be uploaded to a new conversation in another personal account, but the process does not recreate the old chats in the destination account’s history.
What to check before bringing them in
- Source eligibility: The export should come from an account described as eligible. The cited guidance does not state what makes an account eligible.
- Destination: The described destination is a new conversation in another personal account. The old chats are not recreated in that account’s history.
- Purpose: The export is reference material for the new conversation, not a full account migration.
- Technical requirements: The cited guidance does not state an accepted file format, size limit, compatibility condition, or other upload requirement. These details need to be checked before the file is brought in.
What still needs confirmation
The cited guidance confirms the basic method and the limitation on history, but it does not state what happens to the uploaded export afterward. It also does not specify access, privacy, retention, deletion, or attachment-handling rules. Readers who need certainty on those points should check current account settings and applicable documentation first.
Until those points are confirmed, the upload should be treated as a reference upload—not as a way to rebuild the destination account’s history.
