Windows 2008 running AD and file server fail-over cluster in-place upgrade to 2012 possible?
I have three 2008 DC Active Directory servers. Two of the servers (physical) are also a Microsoft clustered fail-over file servers. I am thinking of performing an in-place upgrade to 2012. Is this a possible upgrade path due to AD and File server roles and features installed?
Thanks,
Milty

Milty60Domain Controllers are usually best done by provisioning new servers.
What are your domain/forest function levels? Is this a previously upgraded environment (i.e. do you need to run dfsrmig first?)?
My domain has not been previously upgraded. Both function levels are at Windows server 2003. I do think I will need to run dfsrmig. I am considering provision new servers - its a cost issue.
Thanks for the link. I'm checking it out now.

Milty60 I would take domain/forest levels to 2008 R2 (are you using R2 rather than 2008?) Then run DFSRMig, then work on upgrading to 2016/2019
