Just finished another round of cPanel to DA migrations for email only servers and thought my feedback might be of value both to leadership and other users, as the cPanel to DA conversion script has been updated since my last bit of feedback.
Two significant things failed:
- Subdomains that were added as Addon Domains in cPanel ended up missing (I intentionally instruct my users to do this and cPanel does allow it, long story but legit use case)
- Catchall emails did not migrate
Email filters not migrating remains relevant to note but not something to hope for a resolution, that's not a reasonable thing to migrate.
