What are your tips for successful migration for dovecot (atrpms , 
atrpms-testing depot for centos )

I tried on my personal machine and the command cites wiki returns 
errors on the terminal
what to do with errors: correct the error in the configuration file ?

the question may seem simple but it is not pointless

What errors? They should be warnings, and you can simply ignore them. It just
warns about each setting it changed to the new format.
