Use the information in this section to upgrade to OpsCenter 3.0 from 2.1.x, 2.0, 1.4.x, or 1.3.x.

To upgrade to OpsCenter 3.0:

These steps describe installing the new OpsCenter package and restarting the opscenterd daemon.

On the OpsCenter daemon host, run the appropriate command to update the packages:

Debian/Ubuntu:
```
# apt-get update
```
RHEL/CentOS:
```
# yum clean all
```
Install the upgraded OpsCenter package:

Debian/Ubuntu:
```
# apt-get install opscenter
```
RHEL/CentOS:
```
# yum install opscenter
```
If the package manager prompts you for options regarding opscenterd.conf, choose to keep your currently installed version.
Restart the OpsCenter daemon.
```
# service opscenterd restart
```

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/ssl.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 UI or by manually installing from the new tarballs.
