I assume that you have one machine more than the permissible user number. Or may be just one old and one new machine.
When I did this, I just installed the software on the new machine.
When you go to activate it, the Trend site picks up that you have the software still on another machine.
It then offers you a choice to deactivate the old machine's subscription. (The software can stay on the old machine, but no more updates. The old machine is now shunned.)
The new machine then can be assigned the remaining subscription. You assign this, it activates, you update.....away you go.
