# Upgrade IDOL Data Admin

You can upgrade IDOL Data Admin to the latest version by installing the new version in the existing directory. The installer updates the installed files.

NOTE: Before version 11.3.0, IDOL Data Admin was called IDOL Search Optimizer.

Before you run the new installer, Micro Focus strongly recommends that you move or delete the `config.json` file from your home directory.

If you attempt to run IDOL Data Admin with a version of `config.json` from an earlier version, it might have unexpected results.

When you start the new version of IDOL Data Admin, you must run the configuration wizard. See Edit Configuration Settings.
