Here is what we have
1) not too old copy of the openacs.org database
2) not too old copy of content-repository-content-files directory
So, mainly we need a script that can extract the data from the database for the file storage files, acs_objects, cr_items, and cr_revisions rows and write a sql script we can apply to the live site.
Then we can do something like 1) backup content-repository-content-files on live site, 2) copy over old content-repository-content-files, 3) done, we have the backup in case someting went wrong.
