Is migration of users and email boxes only possible by using the "looking to restore" button for restoring full Cloudron backups?
Yes.
@davejgreen said:
And is that button only available when you first install Cloudron?
Yes.

We have a second server up and running with a newer version of Ubuntu and Cloudron and were thinking about importing each app individually (after backing it up from the old Cloudron onto a backup site hosted on the new Cloudron), but I'm not sure if there's a way to import the users and email boxes? If not, I guess this approach will not work for us, we'd have to use a third site for a full backup.
This is not recommended.
The new server should be installed with the exact Cloudron version you are currently using.
Otherwise you wont even be able to restore the system backup.

Do we need to purchase another one for the new Cloudron instance?
No.
Once migrated simply write a mail to support@cloudron.io and inform us and we will switch the licence to the new server.
To minimize downtime use the dry-run backup restore option: https://docs.cloudron.io/backups#dry-run-restore
This way, you can restore the whole system, without changing DNS records and can validate each app / step manually.
The old server stays up and running, serving all the apps, mail, chat etc.
After a review of the migration, when ready to switch permanently, go to Domains view and click Sync DNS.
