Transferring the License to Another Server
Sometimes, you may wish to transfer licenses from one Parallels server (source server) to another (destination server). For example, this may be the case if the server where the license is installed starts experiencing problems or requires the hardware upgrade.
The procedure of transferring a license from one Parallels server to another depends on the license type and can be one of the following:
Activation with a product key
If you have activated your Parallels Server Bare Metal installation by means of a product key, you can transfer the installed license from the source to the destination server as follows:
- Remove the installed license from the source server (e.g., using the
- Log in to the destination server.
- Install the product key on the destination server. Detailed information on how to install Parallels Server Bare Metal licenses is provided in Installing a License.
Activation with an activation code
If you have activated your Parallels Server Bare Metal installation by means of an activation code, you can use the
vzlicupdate utility to move licenses between Parallels servers. For example, to transfer a license that has been installed using the
XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX activation code, do the following:
- Ascertain that the source server is shut down, or the license is removed from this server.
- Make sure that the destination server is up and connected to the Internet.
- Log in to the destination server (e.g., via
- Execute the following command on the destination server:
# vzlicupdate -t -a
vzlicupdate sends the activation code to the Parallels KA server, thus informing the server of its intention to transfer the license to a new Parallels server. The KA server verifies the received code, generates a new license file, sends it back to the destination server, and installs it there.
Note: Your physical server must be assigned at least one public IPv4 address for the correct operation of the
You can check that the license transferal has completed successfully using the
vzlicview utility. For example:
