Still no luck.
I have the backward migration in my 16 object.
I save the 16 file as a version 15.
Open it in 15 and of course it still loads the 16 library – new object missing from the version 16 library.
I remove the 16 library and load the 15 library that only has the old object and nothing – version 16 object reports as missing.
Even if I have both the old and the new object loaded in the 16 library it isn’t converting the new object to the old one.
