Issue Importing Onyx fullbackup into Obsidian fails

[Demmerle IT]

Hello,

i want to import a Onyx Version 17.5.3 (Ubuntu 16.04) fullbackup into a Obsidian Version 18.0.33 (Ubuntu 18.04) clean install. Both Web Host Edition.

I added the fullbackup via

PLESK_BACKUP_PASSWORD="xxxxxx" plesk sbin pmm-ras --import-file-as-dump --dump-file-specification /root/backup_2102020950.tar

to the Backup Manager.

When i try to restore from this backup, i get the following error for every customer:

An error occurred during customer account creation: Unable to set login or password argument: Do not use quotes, space and national alphabet characters in a password.
The password should be between 5 to 255 characters in length, and it should not contain the username.

I already have changed the security policy to low - no change.

Any ideas?

Regards
