If you are planning to migrate to another server or you have performed an upgrade to your SQL Server, you will need to reset your COZYROC License record for the machine ID on the old machine (or SQL version) and then request a new license key on the new server (or SQL version). By resetting your license record, you are freeing up a license key slot associated with your license record so that you have an available license key available to use on the new or upgraded server.
Before you upgrade SQL Server and relicense the SQL Server version, be sure to save the COZYROC license.dat file from the server being upgraded or decommissioned until you have completed the migration or upgrade. Backing up the license.dat file will save you a recovery step later.
Note: In the past, it was necessary to send the License.dat file to COZYROC support. That is no longer necessary, although you will need the License.dat file to reset your License record via the License Customer Form. For more information about using this for, see the article "How to use the License Customer Form".
