Re: Python-3-Migration of existing Data.fs

Hi,

I’m trying to migrate my Data.fs. 
I use your code, but I’m stuck with a non expected problem.

Using python2, my oid are pickled in a format 
"U\x08\x00\x00\x00\x00\x00\x00\x03\xeaq\x03"
The format seems correct, but is not understood with python3 : 
UnicodeDecodeError.

I was expecting to have problems with data, not oid. Did you face this 
problem?
Did you succeed in your migrations?

Regards,

Arthur
