Move mailboxes to different domain within same account?

Hi, I have 5 mailboxes setup in MXroute under old domain ( Business is re-branding to a new domain ( under same MXroute account and they don’t want to lose email. Is there a way to move/migrate mailboxes from old domain to new domain?

You can rename the domain in DirectAdmin. The changes to the addresses on it will be relative.

Thanks Jarland…not sure how I missed that option, worked like a charm!
