DrPerceptron Posted October 22, 2013 Posted October 22, 2013 Looking at doing it this week or next. Just wondering if anyone has done it already, does it support the Office 2010 KMS patch? (I haven't found much concrete info googling yet) Is anyone using DHCP Failover and upgraded without breaking the relationship?
smithson83 Posted October 22, 2013 Posted October 22, 2013 I too am tempted with the extra features of R2, but am hesitant to make the jump in case it breaks something major.... Just got our new, Fully Virtualised 2012, Servers installed over Summer Hols
mrbios Posted October 22, 2013 Posted October 22, 2013 Waiting for esxi 5.5 support from either nakivo or backup exec so i can have vmware support for it before i start upgrading to 2012r2. quite eager to get started though
FN-GM Posted October 22, 2013 Posted October 22, 2013 Is Server 2012 R2 a supported OS on ESXi? I didn't see it on the OS list on my 5.5 when i upgraded.
mrbios Posted October 22, 2013 Posted October 22, 2013 (edited) Is Server 2012 R2 a supported OS on ESXi? I didn't see it on the OS list on my 5.5 when i upgraded. I thought it was but maybe not? I'm still on 5.1u1 until my backup systems support 5.5. That said....im considering the switch to hyper-v 2012r2, only actually works out about £400 extra on our volume licensing compared to however much vmware is (which i need to check tomorrow) and the features seem pretty evenly matched now. vmwares still quicker and more refined but the savings and speed ms are improving hyper-v is ompressing me. saying all that im looking at ditching backup exec in favour of DPM too so i could be aiming for a 100% system center site at this rate EDIT: oh that's annoying, when i post from my phone the thread doesn't go into my subscribed threads EDIT2: so much for the hyper-v plan. Currently using virtual appliances for nakivo and aruba clearpass...clearpass doesn't support anything except vmware Also got a VA for foldr soon and I'm not sure that has anyhting but vmware support. Maybe one to look at in the future though i suppose. Edited October 22, 2013 by mrbios

VMware Compatibility Guide: System Search According to the VMware site it is... (5.1 too). Yes, DHCP Failover is in 2012. It's not instant failover (maybe you can set it like that?) > Ensuring High Availability of DHCP using Windows Server 2012 DHCP Failover - Microsoft Windows DHCP Team Blog - Site Home - TechNet Blogs 1

jamesfed Posted October 22, 2013 Posted October 22, 2013 Quite keen on the web application proxy feature and will be playing around with the business skydrive uber thingy Quite a way off any big roll out though.
apeman Posted October 22, 2013 Posted October 22, 2013 DHCP Failover is in 2012 Yes its not instant failover but works very well and much better than 70/30 or 50/50 split scopes between server. You also get the added powershell commands

DrPerceptron Posted October 25, 2013 Author Posted October 25, 2013 Looking at doing it this week or next. Just wondering if anyone has done it already, does it support the Office 2010 KMS patch? (I haven't found much concrete info googling yet) Download Microsoft Office 2010 KMS Host License Pack from Official Microsoft Download Center This version of the Office 2010 KMS Host works (the one in VLSC does not). Once installed, dlv d[...] shows Remaining App rearm count: -1 Remaining SKU rearm count: -1 But the rest of the dlv output looks correct and when I threw a room of machines with office 2010 on at it, they all re-licensed happily (according to VAMT) Some extra info here on the SKU/app thingy which I don't know what it is > Office 2010 License Pack on KMS I'll post back on Monday what happens with the upgrade of an actual DC in DHCP failover mode though.
Michael Posted October 25, 2013 Posted October 25, 2013 If anyone is interested in the 2012 DHCP Failover stuff - Step-by-Step: Configure DHCP for Failover I'm struggling to see what the difference is between this and DHCP with Conflict Detection enabled? If one DHCP Server isn't available, the other online server gives it an IP. I've had this setup for years since Server 2003.
nickbro Posted October 25, 2013 Posted October 25, 2013 Can you do a simple over the top upgrade? I just upgraded one of DC's and it seem to work ok with the over the top upgrade, just remember to do adprep first. Just upgraded to 2012 R2 because of the Windows 8.1. GPO objects, plus it was quite easy. Had to upgrade System Center to 2012 R2 too, which I'm rolling out to the site servers at our primaries at the moment. Server 2012 R2 will be rolled out after that upgrade has finished to help support Windows 8.1. The DC hosted at the high school for the cluster network (currently just runs the primaries) is a virtual server in hyper-v on a 2008 R2 CC4 server 1

If one DHCP Server isn't available, the other online server gives it an IP. I've had this setup for years since Server 2003. It's generally not in Microsoft's Best Practices info for DHCP for starters. Picking the Failover config in 2012/2012 R2, they replicate the data between each other, so if one does go down, the other knows everything that the down host knew about - which leases are active, reservations etc and can work with the full scope - no requirement for splitting 80/20 etc, so rather than ping and wait for responses to dish out an address, it can just give an address immediately(ish) There's no real difference in their ultimate end purpose, just the way both solutions go about it, the Failover options are more... elegant?

You can dish out the full scope or split the scope 50/50, 80/20, however you like. I agree though that the only difference is the scopes don't replicate between each other. Not a major problem, but that's what the conflict part resolves. As for reservations FN-GM - I usually have a set of IPs I reserve from being distributed - ideal for switches, printers, admin workstations etc...
DrPerceptron Posted October 28, 2013 Author Posted October 28, 2013 Looking at doing it this week or next. [...] Is anyone using DHCP Failover and upgraded without breaking the relationship? So that I can't become the newer, modern DenverCoder9 I did a straight upgrade on both boxes and everything about them is quite happy. The failover relationship continues to work even when one has been upped to R2 and the other isn't. Not that I wasn't expecting it to behave itself, but you never know.
rob998 Posted October 28, 2013 Posted October 28, 2013 I did in place upgrades on both DCs last week. Upgraded from 2008 R2 to 2012 R2. Couldn't have been easier! AD and DOMAIN Prep then run the upgrade. Everything was back up and running in about 30 mins. Backed up the data server VMs using Veeam and updated them from 2008 R2 to 2012 R2 from home. So easy.
internetuser Posted November 19, 2013 Posted November 19, 2013 Currently updating 2x DCs from 2008 and 2x DCs from 2008r2 Had to go to 2008 to 2012 on the 2008 ones first, as it wouldn't let them go direct to 2012r2 for some reason.
Alis_Klar Posted January 8, 2014 Posted January 8, 2014 I always thought it was better to do a fresh install where possible asp with critical systems such as DC's. I am deciding for my new SIMS server what OS to go for 2008 R2 or 2012/R2? If I can do an easy inplace upgrade later I will go for 2008 R2 as 2012 R2 is not supported by Capita yet. All advice gratefully received

All advice gratefully received It generally is, but we found the inplace upgrade worked well. Make sure you have a back up though just incase. We done the upgrade, and ran disc clean up and it just worked. But these are for servers running microsoft products. not sure about 3rd party ones.
Sagima Posted January 8, 2014 Posted January 8, 2014 We have 3 Hyper-V servers, DirectAccess, A RemoteApp server, a DPM server and 2 DCs with 2012R2. We are currently (as in right at the moment) configuring Web Application Proxy to see how that goes. We upgraded the DCs but fresh installs for the rest.
Jose Posted January 8, 2014 Posted January 8, 2014 currently installing 4 2012 R2 physical servers, these will host the 2012 R2 Dcs and one 2008 r2 for sims only issue so far is file copying and network speed if logged on the server, works fine if copying from win 7 to the server
