There are two servers, one having postfix 2.0.3 and the other 2.1.1 version. This is around 7 year old setup and no documentation left. Could someone help me to upgrade the 2.0.3 to 2.1.1 version. I cannot do a 'make upgrade' as these machines do not have a build environment.
Is there practical way to do this upgrade by copying binaries, settings from 2.1.1 server to 2.0.3 server? Also noticed that one uses Berkeley db 4.1 and the other uses 2.7.7.
