I did this when I had a yes/no column that I then decided I needed to add a third option to.
To expand on this, create a custom column with a fixed set of permitted values. Type "Yes,No" as the values (without the quotes).
Once the column is created, filter your library on all the "Yes" entries from the original column. Select all, Edit Metadata in Bulk, and select "Yes" in the new column. Do the same with the "No" entries. When you're done, delete the original column.
