Inplace upgrade 2008 to R2

Hi There!

We have a 2008 x64 std server we are contemplating migrating to r2, and though I suspect it's not recommended, I wondered if anyone had ever done an inplace upgrade from 2008 to 2008 r2 over an rdp connection?

Also is there anything I need to know about before I upgrade from 2008 to r2? Any caveats or gotcha's?

It's a smallish server, 10 users, runs IIS, and our Email via Groupwise and Edirectory, and there are 2-3 virtual machines loaded in VMWare Server 2.01.

It's a ML350 G5 Server I would imagine it would be sensible to run the latest PSP and Firmware Maintenance CD on it. Is there any way to ensure that after the upgrade the firewall for all interfaces is off by default?

You need to know the 2008R2 is 64bit only, so your hardware needs to be 64bit, you cannot upgrade 32 bit to 64bit and if your server will be a VM then the server also need to be VT capable top support a 64bit guest OS.

Other than it should be easy. ;)

Ive just done a stack all remotely over rdp. Things were pretty painless for most apps but the most important thing when doing it remotely is 9 times out of 10 it resets the networking to DHCP so you need to check your DHCP leases after the upgrade is to complete to find the new temporary ip to connect to. I made sure the files for upgrade were located on the server to negate the need for the dvd to be there locally. As mojotech stated you cant go from 32 to 64 bit but a straight 64 to 64 upgrade is fine.

I cant comment on the email or vmware but i use hyperv and did the upgrade as well on 8 servers for hyperv. MS states during the upgrade you should remove the role if using it, but all you need to do is stop the vms running and it goes fine. IIS upgrades so far have been ok on all the servsr..

The only thing I would say is make sure you have a decent backup in case something does go wrong. My only issue I have is the errors and warning the new dc's throw up during startup, but on the whole the os seems to be quicker than 2008. Hope this helps

If you are currently running Hyper-v on the server you want to upgrade please read this.

Actually R2 upgrade is recommend doing an in-place upgrade since R2 is not consider a major release like a new OS would be. R2 expands on the current 2008 technology.

Hi There!

Thanks for your assistance, RDP wasn't a problem, but vmware had to be reinstalled as it broke all the nic settings and all my vm's were unable to get network connectivity.

Firewall settings were left untouched.
I am using 2008 standard with all the latest updates, no VM or domain, or other functions for that matter.  How do I get RC2, not as a Windows Update I now assume?  I am downloading the full R2 DVD ISO from TechNet, is that the correct path to take?

Thanks for any help.

Yes you need to download the ISO. It's not a windows update.
