From an old thread on this topic:

Contact customer service. Give them the serial number of the license you are transferring and the name and contact information of the organization you are transferring to. They will invalidate your serial number and issue a new one for that organization.

Yes, I've transferred a couple of old licenses with no problem. Sony is very generous about this.
