Why the migration error? Why two different versions? They should use the same…
**The new server**
**The old server**

You should upgrade the recipient system before upgrading

As shown per images it should be the same version

They are on different commits of beta10 (check the blue text below the installed version)
Just rebuild the recipient instance and then the migration should work.

The old server: Welcome to Ubuntu 18.04.6 LTS (GNU/Linux 4.15.0-194-generic x86\_64)
The new server: Welcome to Ubuntu 22.04.1 LTS (GNU/Linux 5.15.0-50-generic x86\_64)
Could it be related to that?
I try to rebuild the new server by
```plaintext
cd /var/discourse
./launcher rebuild app
```

No, host system doesn’t matter.

You should install the discourse-chat plugin on your new server before restoring.
That migration belongs to chat, not to discourse core.
