Ah thanks, I will remember that for the future. I just iterated over everything and saved it in arrays, got it working ‘the old fashioned way’. Seems like this should *really* be in documentation because it definitely isn’t!
I don’t think they worked. I had to start over the migration due to a Mysql error and saw again at the 4.4.2 point the renderings are blank (although the data remains visible on the edit side).
