Migration 6.1 -> 7.0 - comparison configuration Error

[scigghia]

Hi,
i'm following instructions on this page: https://doc.therp.nl/openupgrade/analyse.html
but after setup of the two instances, I get this error on target (7.0) server in wizard "comparison configuration"

../server/openerp/addons/openupgrade_records/lib/compare.py", line 216, in compare_sets
if (column['isfunction'] or column['isrelated'] or
KeyError: 'isrelated'

Sorry, comparisons between 6.1 and 7.0 are not supported until you port #384 to 6.1. Or you could revert this change locally in your 7.0.
