I have to migrate my dovecot box to a new one. I would like to know if it’s possible to do this migration with the replication process.

My plan is to activate replication between 2.2.10 server and the 2.3.4 new server.

Then I will update the DNS to redirect the name to new box. Users will then connect either on the new or the old box depending on the dns upgrade.

Does anyone have already experienced such process ? Is there any incompatibility issue ?

Thanks.
