As from DataMiner 10.4, you can use the following package to upgrade the web API and the web apps on an existing DataMiner installation to the latest release.
If you wish to upgrade the web apps but you are still running an older version of DataMiner than 10.4, the server will first have to be upgraded to at least version 10.4.0.
For more information about the web apps, refer to docs.dataminer.services:
