We will be migrating storage from a running VM (Virtual Machine) using VMM (Virtual Machine Manager) 2016. In this Tutorial the customer had two volumes, one specific for Operating Systems (OS) and a second volume just for Data Disks (additional drives on the servers). The goal is to migrate the Data Disk of any given VM to the proper storage.
The first step is to select the desired VM, and right-click on it and click on Migrate Storage.
In the Select Path page. We are going to have a list of all disks being utilized by the VM, in our case we have OS, Pagefile and an additional disk. Click on Browse… on the last disk (data disk).
In the new page, expand the volume (in our case Volume2) and select the folder where the disk will be placed. Click OK.
The changes can be seen on the image below, click on Next.
In order to start, just click on Migrate.
The process may take some time and it will migrate the content on the fly from one volume to another.
