I am trying to migrate my sites and emails from a cpanel host to a new Bytemark cloud hosted server.
I am getting there with the sites, but I am really struggling to get my head round the process for email.
I can see what is needed from the instructions at https://www.bytemark.co.uk/docs/symbiosis/email-setup/, and luckily my existing host is using dovecot, so I think that will simplify things - it is more about how I test the system out before I instigate DNS migration. I can't seem to get access to the mailboxes via the .testing. system for domains on symbiosis. Should I migrate the web dns first, test the mailbox and then once proved, migrate the mail dns MX records?
Might be the sort of procedural help that might be worth adding to the symbiosis guides at some point...
