repeating a migration - what happens to emails?

[finbarr69]

Hi all,

If I migrate a client/domain from one server to a new one (on a different IP address), and due to DNS propagation delays, some emails still arrive on the old server after the migration, can I re-run the migration (emails only) and expect it to merge the new emails in from the old server with any new ones that arrived on the new server?

If not, what is the best way to migrate and ensure that no emails go adrift?

TIA

Brian

Brian, you can just run an rsync on the mail folder from the old server to the new server. The folder it self is:

/var/qmail/mailnames/

Ah! Cool,

Many thanks.

Just a quick note, ensure to include the -a option to rsync to preserve the permissions and ownership. I forgot initially and found emails stopped arriving because the transferred files became owned by root instead of popuser. oops.

Yes,

rsync -az --progress --size-only /var/qmail/mailnames/ * yournewserver.com:/var/qmail/mailnames/
