Change license of an installed system

[ttrebla]

Hi, I have four boxes running QNX 6.3.0 SP1 and I have four different licenses for them. Unfortunately, during the installation process some errors occurred and the 4 QNX ended up with the same license number.

I'd like to know if there is a way to change the license number of this QNXs. I've noticed that the number is stored in an xml file: /etc/qnx/license/licenses. But I suspect that the procedure has to be a little more complicated than only changing this file.

Thanks
