Yep, was going from 4.1.0 to 4.2.
Further notes, during the upgrade it would be nice if it did the following:
* Added in any optional module war files into /opt/dist/gluu/ (this is where scim.war was missing)
* Update the /install/community-edition-setup path (I has to run the script from the ces_current folder that it created as part of the upgrade), the existing setup folder had the old 4.1 files
* I also noted that scim.service did not exist either, so it failed when trying to run self.installJettyService
I did also have a problem with casa post upgrade, showing this error, however I have not logged into it yet
RESTEASY004655: Unable to invoke request: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I hope this is helpful, if there is any other information you require, happy to assist.
