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
