# Upgrade Media Server

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

TIP: OpenText recommends reading the release notes before starting your upgrade. Please read the release notes for every version from your current version to the latest. The release notes might include additional steps that you need to perform.

To upgrade to the latest version of Media Server

1. Make a backup of the following items from your current installation, if they are located within the installation directory:

   - The Media Server configuration file, `mediaserver.cfg`.
   - Any session configuration files, Lua scripts, and XSL templates that you have saved in the `configurations` folder.
   - Your rolling buffer configuration file. The path of this file is specified by the parameter `RollingBufferConfigPath`, in the `[Paths]` section of the configuration file.
   - The scene analysis training directory. The path of this directory is specified by the parameter `SceneAnalysisTrainingDirectory`, in the `[Paths]` section of the configuration file.
   - If you are using an internal database, the Media Server database which contains your training data. By default, the database is named `mediaserver.db`.

2. Install the latest version of Media Server. Patches include all of the files necessary to install Media Server so you can download and install a patch without needing to install the previous major or minor version. (Version numbers are constructed in the format `MAJOR.MINOR.PATCH`).

   1. Download the zip package from OpenText.
   2. Unzip the files into a directory.
3. Copy your files into the new installation, overwriting the files that were installed.

4. 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.
