Hi,

We are using Zimbra 6.0.10_GA_2692.RHEL5_64_20101215170845 RHEL5_64 FOSS in Windows Server 2008 Active Directory Environment with Domain and Forest Functional Level is Windows Server 2003.

If we increase the Windows Server 2003 Active Directory Domain and Forest Functional Level to Windows Server 2012, then Zimbra works fine or not?

Do we need any pre-requirements for this level increase?

Great Thanks,
