After you've got your actual connections sorted you will need to extract the data from access (lets assume you only need one table), store it in memory and then do your checks for uniqueness before passing the results that are OK into the SQL database.
Depending on your data you could potentially handle the duplicates through the use of primary keys and unique constraints in the SQL database. That would speed things up a lot as you wouldn't need to write (and then run) code to check each row against every other row (which gets out of hand quickly as the number of rows increases).
