Environment

HCX 

Cause

The VM's capacity requirement exceeds the available space on the target datastore, which does not have sufficient capacity to accommodate the VM. 

Resolution

Ensure that the target datastore has enough free space available to accommodate the Source VM. In additional, up to 20% extra space may be used temporarily during the migration.
