Eligible to Downgrade Windows Server 2019?

Question

Microsoft

Good day!
Tell me on the right to downgrade Windows Server 2019?
Let's say you have 10 servers and one dual-processor Windows Server 2012 Standard license purchased under the Open License program.
Do I understand correctly that the license agreement will not be violated (and everything will be legal) if you install this Server 2012 Standard on all 10 servers (that is, by activating all 10 servers with one MAK key from this Server 2012) and buy 9 more Server 2019 licenses with the required number of dual-core licenses each (i.e. covering the required number of cores on each server)?

Answer 1

Call MS and ask, the phone is free, they solve such issues very quickly.

Answer 2

Here is an article that says that there is a right to downgrade. But with the activation of a dozen servers with one key, I would clarify ...

Answer 3

You have the right to downgrade Windows Server 2019, but you do not have the right to activate 10 machines with this key. Only 1.
That is, you buy Windows Server 2019 - 9 licenses with a minimum number of cores and number of processes (depending on which processor and how many of them. It should be no less than the cost on your servers), and
you can get the keys and distributions in your account on the VLSC corporate license support portal.
If in your account after the purchase you do not see the opportunity to download the distribution kit and keys, you will not be able to use this version, respectively.
When checking organs for legal use, you will show this account, since you will not have stickers, as well as documents for the purchase of this version.
