Hi

I am running old iRedMail-Pro-MySQL (1.7.0) installation and decided to upgrade all daemons to latest version. First i upgraded OS from 6.4 to 6.5, and tried it to upgrade to latest Pro version (1.8.1). If i understand correct this is not working becase 1.8.1 using "cluebringer" instead of policyd 1.8. So just to clarify what are the needed steps for this upgrade.

1. Upgrade iredmail to from 0.8.5 to 0.8.6 this means
- upgrade roundcube from my current version (0.7.2) to latest version (0.9.5)
- Upgrade iRedAPD (Postfix policy server) to the latest 1.4.2  (Do i need this step ? )
- migration from policyd 1.8 to cluebringer ? (Didn't find migrate tutorial ?)

2. Upgrade 1.7.0 to 1.8.1

My actual question is can i use 1.8.x versions without using cluebringer ? and continue to use my old policyd 1.8 daemon or i need to do this upgrade because next versions of iRedAdmin-MySQL will use cluebringer from now on ?

Thanks in advance
