# Upgrade IDOL Server Components

In general, it is always possible to upgrade a component from an earlier version. However, it is not always possible to downgrade a component by the same process.

NOTE: Micro Focus recommends that you always back up your data before you upgrade a component.

To upgrade a component, stop it and copy the new executable file over the old file. Make sure that the new file has the same name as the old one. Also ensure that you update any libraries that are included in the release package, such as Community security modules, or IDOL KeyView filters.

For some upgrades, the component runs an upgrade process on your data when you restart the server. For more information, refer to the component release notes. If your upgrade skips some versions, check the release notes for all versions between your existing version and the version that you want to upgrade to.
