Circles of 3

So I was a long term Cakewalk user and have the Platinum deal from about 3 years ago. Since the change to Bandlab I haven't used the DAW a great deal. What is the best set up now? Download the latest Bandlab and then add the vsts, syths etc i had with Platinum? Also how is it best to incorporate softsynsts, effects etc i previously bought via cakewalk or other companies?
