Ruben thanks for your help on this.
Let me get this straight about the import. (After I buy the upgrade or full version.)
(Part 1) I am going to go get the classic UBB software and load it on my server. Then import the Data they are giving me from UBB 6.3.
(Part 2) After part 1 is completed. I will do another upgrade to 7.5 and the data will migrate with the upgrade.
