With data, it is almost always easier and cheaper to start clean and import into the new database that to try to fix a badly designed schema and poorly written data retrieval code. Especially true with all the really good new tools for cleaning and importing data.
Facebook's only issue with moving data to a new system is volume - the actual time it would take to copy, clean and test the billions of records and transactions. Another way might be to only put new stuff in the new system, except for the members and archive all the historical posts, as almost all the interaction - adds, comments, shares, etc. is on very recent information.
