asked on AD Domain Controller Windows 2008R2 Upgrade to 2012R2
I have a Windows Server 2008R2 DC, and I want to upgrade the operating system (on the same hardware).
From information on the internet, I have seen how to upgrade Active Directory, though my server also has other roles and features like DNS, Group Policies and File Services.
Will an AD and operating system upgrade from 2008R2 to 2012R2 also automatically upgrade Group Policies, DNS and File Services?

@Alex, I am upgrading to 2012R2 (instead of 2016) as that is the upgrade path. From the various examples I have seen on the internet/youtube, the simple option is to upgrade to 2012R2. You use ADPREP first and then do the normal upgrade. I don't believe you can upgrade directly from 2008 to 2016. After I have upgraded to 2012, then I will actually be going to 2016 as that path is allowed.
All of the examples I watched and read about didn't address any DNS role on the server, which is why I posted the question. Group Policies I can likely just uninstall and add later. So DNS is really my main area of uncertainty.

If you insist on an in place upgrade, to a good backup first so you will be able to recover after things go bad...
Even Microsoft doesn't recommend an in place upgrade on a domain controller...

@Scott Silva,
Understood. I have done a full backup and cloned the drives. Once I get my new hardware in two months, I will do a clean install with 2016 or 2019. I am just not that educated on this and so the easiest option just seemed to be the upgrade path for the time being.

To keep thing simple, you should instate 2012 r2 member server in domain and upgrade AD from there promote it to ADC
Then transfer FSMO roles to new DC, decommission old DC, upgrade / fresh install OS to 2012 R2 and then promote it to 2012 R2 ADC
