In the old days, PCLaw would let you purchase timekeepers and network access (Nodes) separately. Once Lexis took over, this changed and you now have to purchase one license which includes a node and a timekeeper. Since Lexis is trying to get everyone on the same page, you can now upgrade mismatched nodes and timekeepers for free. Lets say you have 4 timekeepers and 2 nodes. You can upgrade and have 4 timekeepers and 4 nodes. If you have PCLaw 8.10 or above, you can just click on Help --> About PCLaw --> License --> Change and it will upgrade for you.
