Hi. Im currently running Kerio Connect 7.1.2 build 2260 with 100 users on RHEL release 5.3 (Tikanga) on a Dell Poweredge 2850 and would like to upgrade to Kerio Connect 8.2.1, or second latest version, if its more stable.

I tried searching for this exact topic on google and on this forum but didnt get any favourable results.

Can I just do a 1 step direct upgrade?
Or do I have to do it in several steps according to the milestones packages? I remember a consultant came in years ago to do it in stages.
What are some things that I can expect to happen?
Can I undo the upgrade if it becomes unfavourable?

Please excuse me if I sound ridiculous cos its the first time Im trying to do a product update on a live email server for my company and I dont wana screw anything up. I'd appreciate any and all advise on this. I figured if I don't start learning to do it, I never will.

I just completed an upgrade (200 users)from 7.4.3 to 8.1.3 on Centos 6

Went flawless but expect some users that have large mailboxes to complain about the time it takes to upgrade their cache.

Best to do it off hours..

Thanks for sharing!

So do you reckon I upgrade from 7.1.2 to 7.4.3 first before doing a direct upgrade to 8.2.1?

I will be doing it after office hours with about 1 hr downtime max. I'll backing up all the mailstore and configs first.

If your users use Outlook, make sure that Kerio Updater Service ( http://kb.kerio.com/product/kerio-connect/email-clients/keri o-outlook-connector/kerio-updater-service-installation-188.h tml) is installed on all client computers before updating the server. Otherwise all Kerio Outlook Connectors must be upgraded manually.

Thanks I was just reading through that!

My users aren't using KOC for now. We're on POP3. Cool

I plan to upgrade from...

... 7.1.2 to 7.2.0 ...
... 7.2.0 to 7.4.3 ...
... 7.4.3 to 8.2.1

I read somewhere that for 8.2.1 running on linux, there are some dependencies that need to be installed prior. Can't remember where exactly I read that.

Probably in the Release notes.

Yup that's where I read it Very Happy

I did the upgrade successfully from 7.1.2 to 7.2.0 to 7.4.3. It was a straight-forward stop kerio-connect service, install update, then restart services.

My next step is to install the linux dependencies and update to 8.2.1.

Just installed sysstat using this link: http:// www.ehowstuff.com/how-to-install-sysstat-on-centos-5-7-linux -server/ and verified its running but when I tried installing KC 8.2.1 I get error:

error: Failed dependencies:
sysstat is needed by kerio-connect-8.2.1.2096-1.i386

Confused

Currently running KC-7.4.3 RHEL release 5.3 (Tikanga)
