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

I'm using 2008 Enterprise servers. I will look into taking the domain/forest levels to 2008. Then run DFSRMig, Then work on upgrading to 2012/2016/2019.

Remember two of these servers are also a file servers fail over clustered pair. I have Googled around and asked IT associates and have had mixed responses - some say you can do the in-place upgrades some say you can not.

Thanks,
