Hello Great Folks!!

We're planning an upgrade of a production Server which is running Windows Server 2012 R2 to Windows Server 2016.

The Server 2012 R2 is a DC, Print and holds a DFS Namespace share, Is anyone aware of any potential issues that will prevent this from going smoothly?

Thanks for your response in advance. 

God Bless.

Paul

I would never do an inplace upgrade if i cloud prevent it, but always would try to put a second one beside it and migrate to that server. Its much more work, but the cleanest way.

Having said that, an inplace upgrade could be an quick way. If possible i would test the inplace upgrade, make a image of the server, convert to vm and then 'test' the inplace upgrade in a lab.

To answer your question, i don't know of any issues but i havent done any inplace upgrades. I would suggest you take a look at whats changed/new in 2016 and look if it hits any of your used roles/services. I know that in dfs there was lots of change and dhcp keeps evolving too.

If you are  upgrading using an RTM 2016 image, you will need to enable and start NetLogon and w32time after upgrade.

+1 for Dennis.

thanks for all your contributions, I've used Dennis-360ict's suggestion at my previous place of employment and it worked a treat and I've suggested it here as well, so it's one of the options we're considering.

I've also done some Googling and found this  https://docs.microsoft.com/en-us/windows-server/get-started/server-role-upgradeability-table but nothing beats real world experience, hence the post and I'm grateful for all your contributions.

wkasdo - thanks for your tip!
