You'll be pretty much on your own if you need support directly from CWP.

1. CWP support doesn't offer support for 3rd party servers like Nextcloud.
2. Or MariaDB 11.x. - They won't even help with support for 10.11.x
3. You'll also get a reply from CWP for AL9 is in beta, and not supported.
That doesn't mean it hasn't been done, or can't be done.
Just means it will put your SysAdmin knowledge to the test probably, and you might be in the CLI allot.
