The easiest thing to do is to link all of the tables in their current location (use Select All) and they will come over with the same names, but with a "1" added to the end of the table names.
Check to make sure you have all the tables by comparing the old ones with the new ones by name.
Then delete all the old links.
Then rename all the new links to remove the "1"
Doing it in these steps will allow you to visually check every step of the process to make sure you are getting everything relinked.
Total time, about 2 minutes if you work slowly.
Everytime you move the back end, you will need to redo this with the front end.
Does this help?
