Select the host or cluster where the virtual machines to be migrated reside. Then, search for the virtual machines by entering their names or UUIDs in the search bar and click the "+" icon in the list to add one or more virtual machines.
At the bottom of the page, view the estimated data space and memory required for this migration and check if there are sufficient resources available at the destination site. Note that different numbers of replicas will result in varying data space, and by default, the estimated data space is calculated based on the thin provisioning policy.
Note:
If the page shows that the data space is 0, check the browser cache and refresh the data.
