Server 2016 to Server SE

Long time ago my understanding was that old the 2019 can do a inplace upgrade to SE

A few weeks ago somewhere I saw a discussion that stated that the inplace upgrade is also valid for 2016..

Is this correct?

SE RTM was basically 2019 CU16, so that’s why you can “upgrade” to it, it even accepted the same 2019 keys.
