#2. I've done it and so has Kent (as noted). Backup and restore to a different/new OS is fully supported - ConfigMgr doesn't care, why would it? The bits are being reinstalled during the recovery. The problem with going from 2008/2008R2 to 2012/2012 R2 in-place is that so many thing change like the IIS version and WSUS version. There's no way for ConfigMgr to handle these things changing - from its perspective - out of nowhere. But in a site restore scenario, the site server is a completely new install so the difference aren't problematic; it's simply installed accounting for them.
The first link that Todd posted below explicitly says this under the section titled Upgrade of the Site Server Operating System: "Install System Center 2012 Configuration Manager with the service pack level that you want and perform a site recovery. This scenario requiresyou to have a site backup that was created by using the Backup Site Server maintenance task on the original Configuration Manager site, and that you use the same installation settings for the new System Center 2012 Configuration Manager site."

Just trying to build a list of options for clients who may not want to pay for a large, complicated SCCM migration, when their main goal is to get Windows 10 deployed :) So right now, it looks like the options for someone who has their primary on 2008R2 are the following. 1. Migrate to a new hierarchy running 2012R2 as the OS. 2. Backup and restore the DB on to a server running 2012R2, keeping the same name and source code. 3. Upgrade OS from 2008R2 to 2012R2, once it I supported by SCCM.

Can anyone provide a location for the support statement about the DB backup and restore on to a new OS? Just watched the session at System Center Universe where Kent Agerlund does this pretty seamlessly, but just because you can do it, doesn't mean its supported, and that you should do it.

Working on scoping out multiple engagements where a client desires to upgrade from SCCM 2012 to v1511, but their Primary Site Server is running 2008R2 as the OS. From what I am reading, 2008R2 will not be supported as a Site Server OS after October of 2016. (https://technet.microsoft.com/en-us/library/mt210917.aspx) It seems that recommending a new hierarchy, and doing a side by side migration is the safest way to go, however I am seeing some people (Jason S) recommending a backup and restore on to a 2012R2 OS. I can't find anything stating where this is a supported action by Microsoft. Thoughts?
