Upgrading postfix 2.5.6 to 2.6

Hi! I was just wondering if there are any major changes in the 2.6 version that makes my current 2.5 configuration not valid or something?
Because I have alot of email accounts on my server and dont really want it to go down.
And is it easy to downgrade back to 2.5 if something would go wrong?
 
You can create a package of the currently installed version using pkg_create -bx postfix. Be sure to also save everything under /usr/local/etc/postfix/. Then, if anything goes awry, you can just pkg_delete -fxi postfix and pkg_add /path/to/postfix-2.5.tbz to install the old version.

I haven't run into any issues doing postfix updates from 2.0 through 2.6. Just be sure to read the changelog online, /usr/ports/UPDATING in case there's anything in there, and watch the logs.
