If you plan on using distributed storage, enable this on the old environment so you can move messages to the distributed storage (I have archive mailboxes there). This way you are only spending time copying recent email.

Hi All,
I need to migrate the complete data & setup/environment from an old dovecot environment to a new dovecot environment.
Old environment details:
Linux OS - Red Hat Enterprise Linux Server release 6.5 (Santiago) Dovecot version - 2.0.9 Postfix version - 2.6.6
New Environment details: ( 2 systems)
Linux OS - Red Hat Enterprise Linux Server release 7.7 (Maipo) Dovecot version - 2.2.36 (1f10bfa63) Postfix version - 2.10.1
In the new environment, I have 2 servers. I have got 2 of the above servers with above configuration and need to create HA/Resilience. I know there is advanced versions in Redhat and Dovecot. As per my organisation's existing support/policy, that is what maximum supported RHEL and official version of dovecot as per RHEL 7.7.
Now my questions are:
I will stop the dovecot/postfix services on the server in old environment. Is it possible to move/copy the complete configuration along with data (directories/sub-directories/users/groups/existing email in new or cur folders/complete email domains along with complete structure) to the other 2 servers in new env? Could you please suggest me the commands or steps follow that?
Now, With the above 2 servers, I would like to create the HA/Resilience. I know there is a Replication options which are there. Could you please provide me the steps/video, how it needs to be done?
I have got the systems and I need to move/copy the environment to a new environment and create the HA/Resilience. I am not sure, how to proceed and what needs to be done clearly? I am stuck here.
Please help me in this step by step procedure.
Thanks, Kishore Potnuru
