I have successfully upgraded the os M2 to os M3 with a few problems, but it is up and running now.

First I saw this error message (integer expression expected), which was concerning, but doesn't seem to have been a problem

I didn't want to make any changes to the existing config so I typed 'a' and pressed enter. This however did not keep my existing config completely in tact.

1. TLS authentication only was checked, but should not have been
2. Antivirus was turned off
3. Spam was turned off and the kill/tag percentages reset to the default (It did remember the subject prefix.)
4. POP & IMAP clear text logins were disabled, but should not have been
5. had to modify saslauthd.conf.in just as I had to in the M1 -> M2 upgrade

zmtrainsa seems to be having issues, but I need to look deeper into that to verify if it is or isn't working.
