We are currently running Kerio Connect version 7.3.1 patch 2 on a Windows XP 32-bit computer. We now want to upgrade to Kerio Connect version 8.0.2.
Is there a better operating system that is recommended to run this version 8.0.2 on?
Back when we installed version 7.3.1 we were told Windows XP was the best.

Hi, mrralan

We don't have a specifically "Best" system. I understand, though, that Microsoft will soon drop support for XP, so this is a good time to look at options.

The most robust version would run under Linux, which should happily handle a large throughput of mail, however not everyone is happy using the Linux operating system.

You could upgrade to Windows 7/8, or a server version, if you wish to stick with Windows, though please be aware that some users have reported Windows 8 to be a bit of a pain to navigate for day to day use.

Or, if you are investing in hardware, a Mac can handle Kerio just as well.

If you let us know how many users you have, plus roughly how much email comes in on a daily basis, we might be able to advise you further.

Do you recommend running it on a Windows 2008 R2 Server?
If so, would we have to purchase a different license for a server vs. the current license we have for a stand alone computer?

Kerio does not base their licenses on the OS that it is ran one, just basically on the number of servers and mailboxes you need.

Personally, I would not use Windows 8 for this. I say that because I am using Windows 8 right now for my daily work machine. As mentioned, it is a bit of a pain for daily use.

I would recommend either 64bit Windows Server (which I am using) or one of the Linux versions suggested by Kerio. CentOS is a good distribution.

Thanks for the helpful responses.
To answer Lisa's question, we have right at 100 users and hundreds of emails coming in a day.
We do have a Windows 2008 server that we could move this to if that is what Kerio suggests.
I would say it would be best to go ahead and move the mail server to a different machine since XP will be no longer supported before long.

notice... i'm not a licensing specialist, but i think :

  1. that desktop OS cannot be used as server ( at least all new MS desktop os )
  2. you would need to purchase 100 Windows Server 2008 CALs ( if you dont have them already )

No, you would not need Windows 2008 user cals unless your Windows Server is also serving as things like AD.

If you don't want to use Linux (OpeneSUSE and centos i'd recommend) then Windows 2008 is fine. We are using it. In fact we used to use OpenSUSE but since Kerio is not supporting for newest versions, I moved to Windows.

Oh and 32bit or 64bit doesnt matter as Kerio don't make use of it. And on Linux it will still need 32bit libraries.

True from technical point of view. Legal point of view is different. I recommend to ask your regional Microsoft representative. Their license agreements are not clear in this and may be interpreted in many ways.

I'm affraid that that's not so simple. Sad

Look at this document from MS (page 18)

Not true, coming soon. The current beta release of Kerio Connect will have a 64bit version to take advantage of more memory. So if you are installing a new server OS, go 64bit.

I didn't know the new release will be 64bit, so yes it makes sense to have the server 64bit if you are installing a new one.
