Dell R710 with Windows Server 2008 R2 as the Hyper-V host running 5 virtual machines.  Heaviest VM is Exchange 2010 with about 20 mailboxes.  Looks like these guys have done a great job of keeping third party software installed on the host to a minimum.

In-place upgrade appears to be the way to go here.  Questions:

1.  Should I in-place upgrade to Windows Server 2012, patch up, then go to Windows Server 2012 R2 then patch up again?  Or should I just do the in-place upgrade then patch up once I hit Windows Server 2012 R2?

2.  The MS Licensing site is giving me only the Windows Server 2012 R2 ISO.  Is doesn't say "WITH UPDATE."  Should I use a "with update" ISO anyway or does that make a difference?

Ik no fan of inplace upgrades, so i would avoid that if possible. Like adding disks for the new os and install on them 2012r2, or exporting the vm's to an external disk, etc. But can you tell why you want to upgrade? 2008r2 is still supported until jan 2020. And if you are upgrading, you could use 2016, it would get you more years out of the lifecycle.

There is no sp for 2012r2, although there is supposed to be a rollup strategy, so everything in 1 latest rollup, but i dont think they are there yet. Not having an updated iso would mean you just have to visit ms update a few times more.

Reason for the in-place upgrade:  This is the second time I've run across a company with a single server that runs Hyper-V.  I don't have a spare server to install new OS on then migrate VM's to.  The physical server is still young enough and warranty has been renewed.  I'm just looking for an easier way to get the upgrade done with less downtime.

Reason for upgrading to Windows Server 2012 R2 rather than Windows Server 2016:  They have a Windows Server 2003 guest but want a 2016 terminal server.  2012 R2 supports both.  2016 does not support 2003 as a guest.

With only 5 VMs you don't save all that much time by doing an upgrade.  That being said, I'm sure it would go fine.  You can upgrade directly from 2008r2 to 2012r2.

Apologies, Wes, but I thought you had to go from:

Windows Server 2008 R2 => Windows Server 2012 => Windows Server 2012 R2? 

It's OK to skip Windows Server 2012?

If you were on 2008, you'd have to go to 2012 first, but 2008r2 to 2012r2 works.  I've done a bunch.

Upgrade successful.  One item of note:  The in place upgrade did not end with Windows Server 2012 R2 having the hyper-v role installed and the VM's mounted.  I had to manually install the hyper-v role and import the VM's myself.  They came up fine, however, and after a few minutes I had the new integration services installed.
