Hi.

I currently have a bunch of domains, one on old google apps domains or
what it was called, own domain in the gsuite/gmail stuff, another
domain hosted on an ms exchange server, and my current newest domain
going to protonmail directly.

​

However, i would need ideas how to setup everything, so that i can
continue recieve emails and somehow switch over to the new mail
servers at protonmail, but also be able to copy and move every single
email and folders that i have saved on both this gmail mails and the
ms exchange hosted. My idea so far is that i more or less connect
thunderbird to my email accounts, and then export/save all the mails
are a seperate file, and when i got the new mail servers up and
running, then i could open these files and copy back over to the new
mail server, using imap.

​

Often my gmail email is either my old login mail, or my default backup
mail to access accounts as example, the ms exchange one is currently
my main email, and i recieve alot of mail here daily.

I know this isn't really 100% selfhost subject, but i feel it still
partly is, just not doing the annoying hard mail security settings
(dkim and such).

​

I will over time, change all those accounts that i can, to my newest
email, update passwords and such.

Look into imap sync. That's how I transfered my mail to a different
provider. Since I was on cloudlfare, I use their mail routing features
to recieve mail from every domain into two mailboxes.
