I'm in the same boat as you, as my whole family has been using a custom domain for 15 years.

What did you migrate your users to? Did you manage to transfer emails/calendars?

iRedMail stack on a hetzner machine. Migrated mails with getmail and dovecot import, but it isn't perfect, and no calendar etc. But nobody is ever kicking me off a platform again.
