Hi all,

We currently have Kerio running 8.1 x86 on a Windows 2008 r2 x64 server. We noticed that there is a x64 client available but we have has a bit of a rough time with Kerio this year after we migrated from our legacy Kerio 6.7 server to Kerio 7.4 at Christmas with random crashes, DNS issues and general complaints from users about bugs in the new webmail so we are a bit worried about making the switch to x64 if there are any extra bugs to be found!

We would be very interesting in hearing from admins who have deployed the x64 client on their Windows servers.

The reason I ask is because our client has about 600+ accounts in it world wide, this causes our server to run at about 2.5gb in ram which may be causing some performance issues as that is about the limit of what x86 can handle.

Also I believe this will fix the error log limit problem as our server reboots when the error log reaches 2gb.

Thanks,
Rob

Hi,

We were running 8.0 x86 on windows 2008 r2 x64 and switched to the 64 bit version for 8.1. Haven't had any issues -- admin interface is notably quicker though, which is nice. We have about 75 active users.

Hi CarsonUK,

We have 210 users. We migrated from the 8.0 x86 version to the 8.1 x64 version on Windows 2008 R2 with no issues.

Hope this helps!

thanks for your replies guys, I'm glad to hear the admin panel geta nice performance improvment, does it make the webmail client any faster? we currently have a lot of users using it in Firefox under RDS servers and it can be a bit laggy so any performance improvements are welcome.

also, any complications in the upgrade process? As far as i know you have to completely uninstall the x86 version and install the x64 correct?

we had kerio 7.4x86 on Server 2008R2 64bit and we upgraded straight to 64bit 8.1 without any problems. You dont need to uninstall 32bit. just install on top of it leaving everything else intact (store path etc) Have a look at the release notes.

Yes, download the x64 version of 8.1 from the Kerio website. Double-click and enjoy.

Do not go through the normal upgrade process or you will upgrade to the x86 version of 8.1.

The only thing that's a little different is that the 64 bit version will install in /program files (x86) if you're upgrading from the 32bit version, but there's no functional effect. Our upgrade from 32 -> 64 was uneventful.

thanks for the feedback guys. Just noticed that 8.1.1 has been released so will look at updating to that with x64 in the near future as it fixes the iCal shared calendars.

Anyone have any feedback on the Webmail client in x64?
