One item of concern was reading a comment that “postfix hands the mail off to dovecot for local delivery” which makes me think I will lose procmail as my LDA. That would be bad.you can certainly upgrade without breaking everything. as with anything else, it just takes some care and consideration. as far as procmail goes, i'd consider losing procmail to be a benefit. why do you think you need it?

I know it seems redundant, and it would be a stepping stone to ensure that current users are able to connect as they do now. (IMAP-SSL with “Password” for either local users or mysql users).does this mean that you want to use dovecot sasl with postfix, for submission, and cyrus sasl with your imap software? it's certainly possible, but i question the actual benefit.
