# Upgrade HPE Media Server

If you have previously installed HPE Media Server and need to upgrade to the latest version, follow these steps.

To upgrade to the latest version of HPE Media Server

1. Make a backup of the following files from your current installation:

   - The HPE Media Server configuration file, `mediaserver.cfg`.
   - Any session configuration files, from the `configurations` folder.
   - Any scene analysis training data, from the scene analysis training directory.

   - If you are using an internal database, the HPE Media Server database which contains your training data. By default, the database is named `mediaserver.db`.

2. Perform a clean installation of the latest version of HPE Media Server.

3. Check the HPE Big Data Download Center and install the latest patch, if one has been released:

   1. Download the latest patch from the HPE Big Data Download Center. Patches are cumulative, so you only need to download the latest patch.
   2. Unzip the files into the HPE Media Server installation directory, overwriting any files that already exist.
4. Copy your configuration files into the new installation, overwriting the configuration files that were installed.

5. Restore or upgrade the database:

   - If you are using an internal database, copy the database file into the new installation.
   - If you are using an external database, you might need to run a script to upgrade the database schema. For more information, see Upgrade the Database Schema.
