So say your custom domain is example.com and you have a user who logs in with [e-mail] that has data in Google Gmail, Drive, Photos and Calendar. What are the migration steps? I'm finding this really confusing.

Backup Gmail and Calendar, switch to business essentials plan, then cloud identity plan, set up email for [e-mail] with some other provider and you can still use [e-mail] to access your old Drive and Photos?

Yeah, those steps seems about right. But you'd probably want to set up the new provider as your first step and upgrade from the legacy free edition as your last step. I also like to point the MX records to the new provider before doing the backup so there will be no incoming messages while the backup is in progress.

Disclaimer: i haven't followed the steps myself since i'm paying for a personal Workspace account since a few years ago.
