I'm considering upgrading to L5, but just want to make sure that I make the best choice. Could someone explain the difference between doing a minimum cross-grade verses upgrading my base package? Presumably upgrading the base package upgrades all of my resources so that they integrate better with the new engine and features of L5, while the min cross-grade does not? But all of my old books will still work in L5 right?
What are the pros and cons of each option?
Thanks for your advice,
Mark
