Resolved Error migrating from Onyx 17.8.11 to Obsidian 18.0.40

[florian.regel]

Hi,

I try to migrate my old Plesk Onyx Version 17.8.11 running on Ubuntu 14.04 to a new Server with Plesk Obsidian 18.0.40 running on a Ubuntu 20.04. .
The initial connection works well, but if I start a migration for a subscription it throws me the following error:

Failed to fetch configuration data from Plesk servers
Cause: [Errno 2] No such file or directory: u'/usr/local/psa/var/modules/panel-migrator/sessions/20211204131550/plesk.backup.source.downloaded.exported.tar'
That is a critical error, migration was stopped.

Looking into the directory I can see, a lot of files has been created but this specific one is not there.
The debug.log of the session shows the following:
