This is just a report, maybe there is something to fix in the upgrade query.
I have a partner where the certificate changed when upgraded from 53 to 57.
I have 2 similar certificates from Edicom, one is called "Edicom EAS" and it's a root certificate, the other is called "edicom eas server".
One of my partner was using the "Edicom EAS" certificate before the upgrade, after the upgrade to 57 I received certificate errors when exchanging data, then I noticed that the Partner's certificate was now "edicom eas server".
This is just FYI.
