For cloud deployments: if supported by the cloud provider, the VE license server instance can be moved to a different subnet, as long as the original instance can be moved.

It is also possible to backup and restore (to the same instance) the license server data. Please note: it is not possible to use such a backup to revert to a previous license version.

However, the following actions will invalidate the license:

1. All supported environments:
   • Copying the license server data to a different instance.
   • Seriously damaging the root filesystem of the license server system.
   • Re-installing the license server system.
   • Copying the virtual machine on which the license server runs. This includes cloning a virtual machine, or recovering a backup into a new virtual machine.
   • Changing the number of CPU cores of the license server system.
2. VMware environments:
   • Restrictions from point 1 above. 
   • If the license server is bound to the ESXi host: using vMotion on the VM in which the VE license server runs
   • Changes to the API interface of the ESXi host or vCenter Server
   • The license can become temporarily unavailable if the user credentials or address information recorded by esxi_bind are changed. In this case, esxi_bind must be run again to define the correct user credentials and address information.
