# ILM Protocol Upgrade

The ILM Protocol version can be updated independently from the controller software.

1. From the main menu in the controller web GUI, go to the Integrated Controller Tool, then go to the Export/Import tab.

2. Select Import, and choose the update file (with file format *tar.gz).

Make sure that the chosen ILM Protocol version is intended for the current controller software version. The installed ILM Protocol version can be viewed by going to Viewing ILM Protocol Status.
