- ensure your hostname (e.g. my-imscphost) resolves into a valid address on your server
- Dist upgrade from debian 9 to debian 10, then directly after that to debian 11.
-- Use `apt-get install -o Dpkg::Options::="--force-confold" --force-yes -y`
- after successfuly dist-upgrade run `perl imscp-autoinstaller -d -n -v`
- after successfuly dist-upgrade run `perl imscp-autoinstaller -r` and answer all questions carefully. it could be possible that you have to enter a new admin for the panel
- you should now be up-to-date
After these steps i got only an error at the end after the message came that everything was done ok.
