Hello,

Our organization is using FIM 2010,  Version: 4.0.3531.2. We are planning to upgrade the Active Directory to 2012. I was wondering if there are compatibility issues and what needs to be done on the FIM side? 

Thank you in advance for any help.

Hello,

Support for AD 2012 was added in FIM 2010 R2 SP1.

So you Need to at least upgrade to that, see: https://technet.microsoft.com/en-us/library/jj863246(v=ws.10).aspx

And if you in the process of upgrading I would suggest to install the latest hotfix after that.

Keep in mind that 2012 R2 is not currently supported (neither AD or Server Version).

Thank you for your reply.

It seams that the upgraded version should be working with AD 2012 R2

Works or doesn't work is very different from supported or not supported.
Peter is correct, 2012 R2 is not supp
