We recently tried to upgrade our "Windows based" Confluence server from 5.1.3 to 5.5. We followed all of the instructions and during the process of the upgrade we recieved a UI dialog box message stating: failing while upgrading the JVM path. When we clicked okay to continue the process continued to copy files until it was done. Apparently Confluence 5.5 is now using Tomcat 7 because we also noticed that the Tomcat path did not get upgraded correctly either.
We have two specific questions:
1. Since we have running JIRA on this same server is it necessary to stop the JIRA windows service while doing the Confluence upgrade?
2. If the JIRA windows service was running would that have prevented the Tomcat instance from getting updated?
