Transferring Licenses Between ESXi Hosts
Product version: 9.1
Last modified: 12 September 2019
How can a license be transferred from one VMware ESXi host to another?
When you create a VM backup or replication job, the product automatically allocates socket licenses to hosts that contain your source VMs.
If you have no more socket licenses left, you can do one of the following:
Edit your existing jobs and remove VMs that reside on a particular host from those jobs.
Delete the jobs that contain VMs that reside on a particular host.
Purchase more licenses.
