I guess this is something that a lot of folks have come across and done successfully?!? My hosting provider needs me to move my VPS to a different hardware as well as doing a system update at the same time (from fully updated Ubuntu 18.04 to new install of Ubuntu 20.04) I have read quite a few guides/tutorials/how to's by now and have a pretty good grasp, but there are a few questions that remain.
Because of the simultaneous upgrade, I can not 'simply' copy the full VPS over, but rather need to transfer single websites (and their emails) to the new machine and then set the DNS records to reflect the change. But here lies the issue. Website/Database is easy, but all my clients have their email programs pointing to a central domain name, which has the SSL certificate. Now if I move the email to the new server and point the MX records there, then things become disjointed. First I thought I tell my clients to prepare and let them set their email programs to use mail.<their-domainname>, but that means they can't use SSL to communicate (wich belongs to the central domain). Ideally the whole move will not include my clients to do anything!, BUT if they do not change settings in their email programs, then incoming mail is on a different VPS than the machine they are contacting to read/send email. Would anyone have a clue of how to avoid this issue? Bonus points for a solution, that does not include my clients having to do anything on their own devices. I will have to think about a solution, where I move the central domain INCLUDING all email files in one go, right? Note: I have full access to both VPS (incl firewall) as well as the respective DNS records.
