Had an interesting dilemma last night, just before cutover to R80.40 I normally collect CPVIEW stats on cluster member still running R80.30 so I have some quick baseline and then also compare connections table on upgraded member.
Funny (not!) enough upgraded member had only synchronised approx half of all connections on all VSes.
Not too sure if screenshot is big enough but it shows that at MVC state connections table is much smaller:
We proceeded just because we had "out of state" connections enabled, so I knew impact would be rather small but still interesting case. Had not noticed that before on my previous upgrades with non-VSX FWs nor other two clusters of VSX.
I even searched for a specific connection that I could find in R80.30 table and it was not present in R80.40
I have checked and most services apart from DNS are synched in cluster.
Was wondering if anyone else has noticed it?
