You may receive an updated license.dat. This could be for a feature upgrade, license extension, or version upgrade.
1. Backup up your old license.dat so you can revert to it should you face any transition issues.
2. Copy the new license.dat in its place.
3. Add any ports or additional options you had specified in the previous license.dat.
The re-read will fail if the new license.dat does not use the same ports as the previous license.dat.
4. Run:
This updates the license server for the new license.dat.
5. When the re-read is complete, the license is updated and ready for use; check the ldra.log file for any errors.
If the license server is not updated after the re-read has been performed, try stopping the license server and then starting it again.
If your license expired, the license server may have stopped entirely; in this case the re-read will not be sufficient to update the license server. In this scenario, you should start the license server.
If a new CTL file was provided with the license.dat, make sure that all the clients are updated to use the new CTL file.
License servers are backwards-compatible.
