Last week we upgraded our Lab Env to 12.1.2 and the DB's to OL8. Tried the in-place collector upgrade to OL8 and only one of the two collectors upgraded. The other is still at OL7. Each collector is in it's own collector group.
We have Windows devices 3 of them at ver 2019, 2016, & 2012 using AD credentials and port 5986. Concurrent Powershell is enabled. The servers were on the OL7 collector and data collection was working just fine.
I moved the Windows devices to the Collector running OL8 and data collection stopped working. If I disabled Concurrent Powershell for that OL8 collector, data started collecting again. So far I have not found anything in the logs.
Linux and MSSql are working fine with out issue (so far).
Has anyone else seen this with Windows since upgrading DB's and Collectors to 12.1.2 OL8
