After upgrading a 2012 r2 DC to 2019, can I use the 2012 r2 license on a new server?
If it's a retail license then it should be possible. Another option is to install the hyper-v role (as only role) on new host, then stand up two virtual machines. One for active directory domain services and another for application / SQL server. Not recommended to install SQL or other roles / applications on a domain controller.
Dave Patrick The image is from the server. the License URL says Retail; so that makes me think it would work.
OEM:SLP: This key comes pre-installed in Windows, when it comes from the Factory. This key is geared to work with the OEM Bios Flag found only on that Manufacturer's computer hardware. So assuming you installed to the same hardware it should be fine.
- Well that sounds like my original plan would not work then. Would it be bad for server 2 with SQL Server and Windows Server 2019 to be "below" a 2012 r2 DC?
It shouldn't be a problem. You still have some time.
