Hosting company sold, Omeka was not migrated >.<

My hosting company was bought out and it looks like my install of Omeka did not migrate to the new companies servers. The database & folder appears to still be there. What is the best practice for restoring my database?

Do I:
Re-install Omeka into the same folder?

Rename the original folder then install & copy over some files?

Rename the original database then copy it over to a new database for the new Omeka install?

Some combination of the above?

Any help would be greatly appreciated >.<
