Converting Files from Filemaker 3 to Filemaker 8

My old system 7 Mac has expired, I have invested in a new iMac on OS 10.5, I have also bought Filemaker Pro 8

I have succeeded in extracting the Filemaker 3 files I need to CD, they are copies of the original DB files I need which were in the Filemaker folder, they are in Filemaker format, I still have the option in system 7 of exporting them to comma or tab delimited files, I can also transfer the data to Word 6 and save in that format.

Do I design a database in Filemaker 8 which is a mirror of the DB I have in Filemaker 3. What format would be the best to try and import the files into Filemaker 8 or is there another programme that I could convert into and then into Filemaker 8
