Hallo everybody,

to minimize the downtime for an upgrade to KC 9.0.1 I want to:
- install OSX 10.10.5 on an nearly identical mac (MacPro 5.1)
- install KC 8.5.3 (this one we use on our "old" mail-server)
- stop Kerio mail-server
- copy (cp -Rp) kerio directory (/usr/local/kerio) from old mail-server
to new mail-server into same location
- shutdown "old" mail-server
- fill in the right network parameters to new mail-server
- shutdown new mail-server, change (OSX)hard-disk
- update from KC 8.5.3 to 9.0.1

Short explanation: we take the hardware of our old mail-server, only change
the (OSX)hard-disk.
Is this a possible way to press down the offline time to 15-20 minutes?
Or does anyone see any problems in this procedure?

Our environment (old mail-server):
Mac Pro (MacPro5.1)
OSX 10.6.8
KC 8.5.3
Mailstore are on a separate hard-disk

Sorry for my English, hope everybody understand my request.

Yes, these steps are correct. As long as the disk will be mounted with the same path on new server. Otherwise mailserver.cfg may need to be modified accordingly.
Also, any other changes in the system (eg. edu.mit.Keriberos client config file) should be transferred too.
Just make sure that Java 8 JDK is installed on OS X 10.10 before you start installing Kerio Connect 8.5 (Kerio Connect 9.0 no longer needs this requirement).
