I need a full steps how to migrate old server into another server.

Hi,
I need to migrate our mail enable server on another server because old server not responding well.

I need all stesp. as i am trying with KB ME020073, but this is not fully cleared.

No... If you are talking about web-interface (mewebmail), the option to forward mails gets disabled as soon as you select more than a single mail... We are using Server Manager 6.1.76, and this feature is not supported...

Not sure, if newer versions provide this feature...
