Registered licences must be moved before changes are made to a licence database. This includes changing the type, location or name of the database, or changing the IP address of the database server. Whether it is a licence database conversion or migration, the process is the same. The first step is to create a new licence database with a new database connection (FireDAC). It is then necessary to connect to the new licence database and register the products and options with the new database. Switching databases is done using the same "Q-DAS License" tool, which needs to change the connection from the old to the new licence database. The Q-DAS Tools Launcher provides the tools for creating databases and database connections. Link to: Q-DAS Tools Launcher
To move a licence, the licence file (*.LIC) supplied with the purchase is required.
Examples of use cases
This diagram shows a migration of the Access databases and the licence to SQL. The SQL databases were not prepared prior to Q-DAS Setup. Therefore, the Access databases were used for the installation.
In this example, the Q-DAS applications and databases are located on separate servers. The database type is changed from Oracle to SQL. To deploy the Q-DAS applications, the database connection and the licence registration must be adapted.
The renaming of a provisioning platform is shown in this diagram. When a licence is registered, the licence database and the platform used are linked (encrypted).
Before making any changes to the database connection, the licences must be unregistered. In this case, it is essential to carry out the steps described. Once changes have been made, deregistration is not possible. Unless the customer's internal IT department reverses the change. If this has already happened, it can only be resolved by a Q-DAS application engineer or by contacting Q-DAS sales with a request to unlock previous registrations. The licence database must then be reset and the initial registration carried out again.
Release of licence for use ("old" licence database)
Start the "Q-DAS License" tool. 
The tool displays the currently registered products and options.
Select the licence file (*.LIC).
To release the used licence, deselect all of them and click "Register".
To verify that the licence is released, restart the "Q-DAS License" tool. It should be empty.
Change the connection to the "new" licence database
FIREDAC
Register the licence for use with the "new" licence database
Start the "Q-DAS License" tool. By modifying the FireDAC INI file, the tool uses the connection to the new licence database.
The tool displays the currently registered products and options. Select the licence file (*.LIC).
Select the products and options required to be available on this platform and click 'Register'.
To check that the licence has been registered, restart the "Q-DAS License" tool. It should display the selected products and options.
