I'm currently monitoring my box now after doing the migration from 
2.1.16 to 2.3.1 this morning. Things look okay here. I see the reply 
flag on a few mails I have in my own mailbox. I don't think I set 
anything as 'important' though. Maybe you mean \Flag ?

I choose to NOT do a reconstruct -r on 2.1.16 prior to moving the mail 
spool to 2.3.1. Instead after moving to 2.3.1 I used a perl script to 
login to each acct, select the INBOX, and read 3 headers before logging 
out. Monitoring output of the cyrus log didn't show any problems so I 
figured there was no need to go back and run reconstruct under 2.1.16.

That said, it's to early to say one way or another if it's a success, 
that'll come Monday when the bulk of the users hit the box!
