Update

New versions of the platform are usually released every two weeks. Updates may include:

• new features;
• improvement of existing features;
• changes in some of the principles of operation;
• correcting errors that occur during the operation of the product.

When an update is released for VMmanager, a popup message "The new version is now available" will appear in the platform interface. 

Limitations and possible issues

• You can update the platform only from one version of DCImanager 6 to the latest version if you have a valid license.
• Updating from VMmanager 5 to VMmanager 6 is not supported. You can migrate from VMmanager 5 using the instructions.
• Updating the platform on a CentOS 7 server may cause platform malfunctions. Before upgrading, migrate to AlmaLinux 8 using the instructions.
• If the platform version is lower than 2023.01.1, the update will install a new version of the task processing service. Running tasks will be forced to terminate. It is recommended to perform the update when the number of running tasks is minimal.
