Pre-requisites

Before beginning with the process of upgrading, ensure that the following pre-requisites are fulfilled.

Configuring Proxies and Repos

You are required to configure the proxies and repos.

Configure the http proxy in /etc/yum.conf file and also export the proxy's address to the environment.

In /etc/yum.conf, add the following line:
```
proxy=<proxy_server>
```

Export the proxy's address.

export http_proxy=<proxy_server>
export https_proxy=<proxy_server>

Creating a Backup before Upgrading (Optional)

This procedure is optional but is recommended.

Session Monitor enables you to back up the Configuration, Database, Block Storage and essential Session Monitor files of the Session Monitor Servers by providing a Backup and Restore procedure. For more information, see the Session Monitor Release 5.2 Backup and Restore Guide.

Note:

Currently, there is no rollback option available from an upgrade.

A Note if you Have Not Taken a Backup

Create Historical System Diagnostics with the Create savepoint and Include mysqldump check boxes enabled from the PSA Page. This is mandatory.

Download a copy of the Diagnostics created and save it in a safe location. These diagnostics are required to debug any issues in the future.

For more information, see the System Diagnostics section in the Session Monitor Release 5.2 Installation Guide

Note:

Creating the Savepoint is applicable only for the Mediation Engine. Also, enabling the Create savepoint and Include mysqldump check boxes is mandatory for taking Diagnostics.
