Two node DAG Exchange 2013 CU23.
I have an expired OAuth certificate on both nodes when I run Get-AuthConfig | FL.
However, I also show in ECP an OAuth that doesn't expire until 2026. (Ran into the the OWA issue back in April. Got things working by getting the old cert configured on both servers again.)
Questions.
Can I just run Set-AuthConfig -PublishCertificate to get the NOT EXPIRED cert in ECP to be the OAuth certificate?
and then run Set-AuthConfig -ClearPreviousCertificate to delete the expired cert?
then run IISreset or reset application pools
Question 2.
I assume I need to do all these commands on both nodes?
Reason.
Trying to bypass the replication delay before patching.
