# Upgrading Nx Witness

Navigation: Working with Nx Witness > # Upgrading Nx Witness |

Nx Witness provides a one-click upgrade for an entire System, including Systems on different platforms, locations and devices, without the need to physically login to the computers that Servers are installed on.

When a new version of Nx Witness is released, a notification will open in the Client. You can click on the appropriate link to perform the upgrade, or you can disable future notifications of this type. If a new build is released to fix a particular issue, the support team may recommend that you upgrade to a particular version.

The upgrade process can take some time. Issues may occur during the upgrade process for a variety of reasons. The most common problem occurs when a Server goes offline or becomes inaccessible. In this case, try to repeat the upgrade.

IMPORTANT: Ensure that all servers in the System are upgraded.
