Hello,
I know that this is an unsupported version, however, I have a legacy system that had this version uninstalled as part of a trouble shooting process. There should have been a copy of the installer available locally, but somehow that was missed.
1) is there a server installer download available in a legacy repository
or
2) Could using 2019, then restoring from a backup that is 2020.3 update the server?
Thank you,
rdt
