Yes there is no errors in the vent log. That is the issue everything installs fine you can see it updated by looking at add\remove programs, it shows 5.3 is installed.
This is one of 4 connection servers that we have in a replicated group. But per the 5.2 install instructions I get to the point where you are supposed to test the connection after the upgrade and I get no connection. So at that Point I have rolled back.
