Upgrading tarball installations

Procedure

Download and extract the new tarball.
Copy the following files and directories from the old tarball installation directory to the new one.
```
conf/clusters/*
conf/event-plugins/*
conf/install_id
conf/log4j.properties
conf/opscenterd.conf

ssl/*
```
Stop the opscenterd instance (if it is running) and start it from the new tarball installation directory.
Upgrade the agents either through the GUI or by manually installing from the new tarballs.
