A couple of migration scripts that were made for very specific changes that we've gone through during the development and evolution of our functional model:

• updateCanonicalStrings.php: This one was made to migrate all ZObjects when we changed from having references in Z2K1 to having string identifiers
• updateTypedLists.php: This one (the most recent) changed all simple arrays with benjamin arrays.

These should be removed as they are not necessary anymore.
