Managing Licenses 157
Updating the Current License
In Parallels Server Bare Metal, you can use the vzlicupdate utility to update the license
currently installed on the Parallels server. When executed, the utility tries to connect to the
Parallels Key Authentication (KA) server and to retrieve a new license and install it on the
server. To update your license, do the following:
1 Make sure that the Parallels server where you wish to update the license is connected to the
Internet.
2 Execute the following command on the server:
# vzlicupdate
Start updating license [6E62.3D01.6BEC.E8D7.CE42.4517.68CB.E102]
...
By default, vzlicupdate tries to access the KA server having the hostname of
ka.parallels.com. However, you can explicitly specify what KA server to use using the -
-server option:
# vzlicupdate --server ka.server.com
In this case, the vzlicupdate utility will try to connect to the KA server with the hostname
of ka.server.com, to get a new license from this server, and to install it on the server where
vzlicupdate has been executed.
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:
 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 vzlicload -r
product_key command).
 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 (p. 156).
 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:
1. Ascertain that the source server is shut down, or the license is removed from this server.
