If you check the post above:
 * Renaming videos with special characters: Wednesday March 21 - We anticipate this taking a couple of days. We will be going wiki by wiki, starting with the wikis with the most videos.
 * Data migration - We are hoping the last week of March or first week of April.

I'll keep updating here as the changes occur.
