Upgrading the DataMiner web apps

From DataMiner 10.3.0/10.3.3 onwards, DataMiner web upgrades are available separately from the general DataMiner upgrades. These updates include only the web API and the web apps, leaving all other DataMiner processes untouched. This way you can get access to the latest features and enhancements of the web apps without having to do a full DataMiner upgrade. The web upgrades only require a brief installation and do not necessitate a DataMiner restart, ensuring uninterrupted monitoring and orchestration.

Note that it is not possible to upgrade the web apps to a DataMiner 10.5.x version or higher if the DataMiner Agent itself is still running a DataMiner version older than 10.4.0/10.4.1. To install a 10.5.x web upgrade, the server must first be upgraded to at least version 10.4.0.

Note
  • Executing a DataMiner upgrade will override any DataMiner web upgrades that have been performed in the past.
  • New web functionality that depends on new features in the core processes will not be available until you have also upgraded the core software. For example, GQI is part of the core DataMiner software, so new GQI features will only become available with a full DataMiner upgrade.
Tip

You can download the latest web upgrade package on DataMiner Dojo.

Automatic backup

From DataMiner 10.3.11/10.3.0 [CU8] onwards, whenever you upgrade your DMA or install a DataMiner web upgrade, an automatic backup of all existing dashboards and low-code apps on the system is generated and stored in C:\Skyline DataMiner\System Cache\Web\Backups.

After the upgrade process, your dashboards and low-code apps may be migrated to ensure compatibility with the updated software version. If an error occurs during this migration, or if you need to perform a DataMiner downgrade, you can manually restore your dashboards and low-code apps from the backup.

Note

The Backups folder retains only the five most recent backup files.

Downgrading the DataMiner web apps

Since dashboards and low-code apps can automatically get migrated after a software upgrade, these will then no longer work in combination with older versions of the software.

To deal with this, after a downgrade, follow the steps below:

  1. Optionally, create a copy of the current files in C:\Skyline DataMiner\Applications and C:\Skyline DataMiner\Dashboards.
  2. Go to C:\Skyline DataMiner\System Cache\Web\Backups and locate the most recent zip package (or the zip package that originally got created on the version you have now downgraded to).
  3. Extract this zip package in C:\Skyline DataMiner and let it replace the files in the Applications and Dashboards folders.
  4. Do the same on every DMA in cluster.
Note
  • Any changes that have been done on the dashboards and low-code apps after the backup was created will be lost.
  • New web functionality that depends on new features in the core processes will no longer be available.
