I have become the admin of the OpenNMS installation here.  It has been neglected for a while - hence the old versions.  How can I upgrade the version of it with breaking the installation?
OpenNMS version
Java version
Operating system
Red Hat Enterprise Linux 6.8
PostgreSQL version

Actually, I decided that rebuilding it with OpenNMS 18.0.2 was best - I took a list of the admins & the nodes it knew about and am just waiting for our server team to finish re-imaging and patching it.  Once they're done, I'll install it fresh, following the installation guide on the wiki.

Thanks for your help!
