Hi,

Some customers do not upgrade their kerio connect servers with every new release! So I have sometimes the question: can I upgrade to the newest version without any problems?

In the current case we have Kerio Connect 7.3.2 installed and what to upgrade to the newest version(8.X). Is this possible? Do we need to upgrade to 7.x before? And what about the users pcs (KOC), will be only the client upgraded or do they have to sync all items new?

Any ideas?
Greetings from germany

The upgrade from 7.x to 8.x shouldn't be a big deal. With 8.x you have the option to use a 64-bit version. I upgraded from 32-bit 8.x to 64-bit 8.x very seamlessly. Going from 7.x, you may want to make a backup of the server.cfg and users.cfg file before doing the upgrade, just in case.

Clients using the off-line connector will have to be upgraded, but that should happen auto-magically when they start Outlook after the upgrade.

I would update to 7.4.1 and then update to 8.3. Make backups in between if possible.

Hmm,
sounds to me that there is no real upgrade path from Kerio.

What does Kerio Connect Support say to this issue?

Backup - of course
Direct upgrade to Kerio Connect 8?

Hello abirkner,

HoosierMac is absolutely right. You should find the actual installation of the newer version takes only a few minutes.

There are post-installation processes that go on in the background once the upgrade is installed. These may slow the server performance.

You should also watch out for the size of your logs folder, as the newer version of Kerio Connect indexes all old log files so that they can be read as one contiguous file. It might be worth deleting old logs, or moving them to a separate location, as the indexing process can give the impression that Kerio Connect has stalled.

Finally, it is important that your Software Maintenance is current, otherwise you may not be able to upgrade to the latest version.

I hope this helps.

Best regards,

Neil.

Hi,

"HoosierMac is absolutely right. You should find the actual installation of the newer version takes only a few minutes."

That's true... We have a Linux based Kerio Connect Installation for internal use that takes us only minutes to upgrade. That's not the Problem with Kerio Connect!

Usually there is no Problem to upgrade from Version 1 to Version 1.1 for example. Usually we know that the Client-Upgrade (KOC) will work like a charme after server-upgrade. But in this case the question is:

Should we upgrade in steps like: 7.3.2 to 7.4 to 8.3?
What will happen with the KOC-Client-Upgrade? After Server-Upgrade! Can there be an issue because we upgraded the Server in one big step! (from 7.3.2 to 8.3)
Customers don't like if the IT will drop there performance for one day because the KOC will upgrade and then 25 Users have to sync their complete Mailbox from Server to Clients again!
(Because of KOC Structure update or something like that)

I hope that clarify my questions!

Personally I always recommend users to go to the last release of the previous version before making the jump to the latest release; so in this case go to 7.4.3 then 8.3.0.

Note my previous comments about post-installation issues, so maybe schedule the upgrade over a weekend, or when there are fewer users for a good few hours.

You will need to upgrade KOFF - this can be automated via the webadmin interface, or you can do it manually.

It is recommended that users switch to webmail whilst their KOFF upgrade is going on.
