Can you please open a github issue for this upgrade? Here is the tree of [Community Edition Gluu Server](https://github.com/GluuFederation/community-edition-setup/issues).
>> Is there any other way to upgrade to new version?
Alternative way is not easy but you can try...
1. Get oxAuth war from: http://ox.gluu.org/maven/org/xdi/oxauth-server/
2. Get oxTrust war from: http://ox.gluu.org/maven/org/xdi/oxtrust-server/
3. Rename these downloaded copy to 'oxauth.war' and 'identity.war' respectively.
4. Delete 'oxauth' and 'identity' directories from /opt/tomcat/webapps/ ( backup them if you have any valuable modification )
5. Put newly downloaded artifacts in /opt/tomcat/webapps/
6. Restart tomcat.
