Guestbook owners can transfer a guestbook to another existing Tools user from the guestbook management page.
The transfer changes the actual owner of the guestbook. The guestbook itself is not copied or recreated.
The following stay attached to the same guestbook and therefore move with it:
The previous owner's historical API key association is cleared during the transfer. Historical entry provenance remains unchanged.
The destination account must exist and be enabled.
After a successful transfer, the new owner receives the guestbook management and moderation permissions required by the service. The previous owner no longer has normal owner access to that guestbook.
A transfer is rejected when:
Guestbook ownership is always determined by the guestbook's current owner, not by historical API keys or previous ownership.
