The updates settings can be accessed via the burger menu. They display details of the currently installed software and any available updates.
There are two separate components shown, each of which might be updatable:
There are configuration options for automatic updates. You can also manually check for updates and apply pending updates at any time. Applying updates either automatically or manually might result in some downtime.
Note: To perform any kind of update the Enterprise server needs network access to https://portswigger.net.
If your installation is unable to contact the PortSwigger updates server, you can perform an offline update of both Burp Suite Enterprise Edition and Burp Scanner. You can manually download updates from your PortSwigger account. Then use the "Upload ZIP file" button to upload the update.

Over time, there might be backwards compatibility limitations on either component in relation to the other. If one component has not been updated for some time, then it might be that it must be updated before any further updates can be made to the other component. The updates page will indicate when this is the case.
Some available updates might require manual intervention preventing them from being applied automatically. For example, if an available update makes changes to the software license agreement, then it may be necessary to accept the new agreement before the update can be applied. The updates page will indicate when this is the case.
