iI have set up a new host for migration. Unfortunately it is not possible to import a backup from the old ciphermail with the restore function via the GUI. The error message is:
You must correct the following errors before you may continue.
System password is invalid
The system password used is the root password of the debian 10 system.
The old System: Version 4.8.0-0 Build 2020-05-19-13:37 / Debian 9
The new System:Version 4.12.0-0 Build 2020-11-17-11:2 / Debian 10
Thanks for Help!
