You've got 2 options:
1. Export and import the LO's that you want
2. If you do NOT need the local LO's anymore you can overwrite the USER-FILES folder and teh local database. But, beware, you will loose access to current local lO's.
a. copy remote USER-FILES ver local USER-FILES
b. export mysql db on remote, and import in local db
c. In management. page, change the site URL, the root_path and the import_path to match the local system.
