I have my old mailbox, which was hosted by my hosting provider. I want to move it to a new one, like G Suite.
To access my old email, I used
I now moved my site to a new provider, so I changed the A-records to point to the new server. Therefore, as I understand, I cannot access my old
imap.mydomain.com because it points to the new IP.
Do you know what I could do, which records I could change, to temporarily point
imap.mydomain.com to my old server, so I could access it via IMAP protocol and use the new email hosting provider migration tool (either G Suite or any other)?
Should I add the A-record for
imap.mydomain and point it to the old server and keep the MX records as they used to be (the old server as well) and migrate the data? Or I don't have to change the A-record and I can just do with the existing MX records unchanged?
