You can upgrade Fleet Manager to a more recent version by following these steps:
Find the Fleet Manager data disk in the resource group where Fleet Manager was deployed, its name should end with “-data-disk”.
Create a snapshot of the data disk. Once the snapshot has been created, click on its “Properties” and make a note of the “Resource ID”.
Delete FM’s Virtual Machine
On the delete confirmation tab that appears, also select the “OS disk” and “Data disks” to be deleted along with the virtual machine.
You do not need to delete the network interfaces or public IP addresses.
Refresh the resource group until the VM and its disks have disappeared from the list of resources.
Follow the guided setup example to deploy the new version of Fleet Manager.
When filling in the Azure deployment template, enter the data disk snapshot’s “Resource ID” in the “Snapshot” field
Once the deployment is complete, the new version of Fleet Manager will be up and running.
