Migrating Server from SLES to Windows


at the moment I have installed Groupwise 2014.0.2 on an SLES11 (on Vmware) and 25 clients (Windows), AD only.
Now the long-awaited SSO for AD comes with GW2014R2, but unfortunatly only, if the POA-server runs on a AD-integrated Windows-server...

So, if want this feature, I have to migrate my server from SLES to Windows.

But what do I have to expect from a GW-server running on Windows? Are there any known issues, which will only occure on Windows? Will I regret the migration soon?

Thanks für your input
