In this dialog box, during the upgrade you can select whether existing chats are to be transferred or whether the data transfer is not to take place.

estos UCServer uses a newer chat database schema than the previous version. Continued use of existing chats is only possible if they are converted to the new database schema.

Depending on the size of the database or system, the conversion can take several minutes and must not be canceled.
A subsequent conversion of the database is not possible.
