Thanks - which zero? (there are two of them.)
You should not change the deriveSafeCopy of your old data type. The only allowed change is renaming your data type (see below). You should increment the version of the new version of your data type, akin to releasing a new version of a library.
Can I really rename old.T => new.T_orig ? It looks as if then tries to load the wrong acid-state snapshot.
The name of your data type doesn't matter as acid-state doesn't store that on the disk. HTH, -- Felipe.
