Migrate
Moving mail in, without losing any
Five connectors, one shape: copy while the old server is still live, change the MX, then sync what arrived in between.
cPanel
Mailboxes, forwarders, autoresponders and filters read from cPanel or WHM, mail copied over IMAP, and the delta synced after cutover.
Plesk
Mailboxes, forwarders and auto-responders read from Plesk’s API, mail copied over IMAP, and the delta synced after cutover.
Google Workspace
Domain-wide delegation, per-mailbox tokens, and Gmail labels mapped onto folders.
Microsoft 365
One tenant-wide token, Graph to enumerate, Exchange Online to copy.
Any IMAP server
A username and password per mailbox, and everything else is the same.
