dovecot - Aug 2017 - 2.1 to 2.2.31 on new server?

I have a Centos 6 server with Dovecot 2.1.17/mysql/virtual domains

I'm setting a new Centos 7 server, and, aim to install 2.2.31 from
Ghetoforge

dumb question, can I install 2.3 on new server, then, copy old
/etc/dovecot tree to new /etc/dovecot ?

appreciate any tips and advice,

There are several config option changes between dovecot 2.1.x and 2.2.x 
(you certainly did not mean 2.3, right?), so you better review your 
current settings and compare them with /etc/dovecot/conf.d/*.conf files 
on a fresh install.

I am always when updating doing a diff between the older version 
original config files and those from newer dovecot release to see what 
kind of option may have changed or have been added.

There are some changes in the config file format, see:
