What I like to see to be added is imapsync for migrating email. This option makes it possible for customers to do the email migration by them self.
it is simple to host it outside
As I stated in another post:
Gilles Lameral's ImapSync - this is the docker version from https://imapsync.lamiral.info; read: https://imapsync.lamiral.info/FAQ.d/FAQ.Docker.txt
Though it is a good idea to go through all the documentation.
We run this locally on our servers for when we need to do single or mass (command line) migrations.
Same. It’s brilliant to have an install of your own running.
