Hi,
Does anyone have any suggestions on how to go about migrating clients with JRE7 to JRE8 using patch manager?
Mike
There's no "migration". They are two separate product installs, just like .NET2 or .NET4.
So... install JRE8, then uninstall JRE7.
Possibly this conversation will be of some assistance: Java 7 to Java 8 Upgrade Package
