Code Issues Proposed changes

Fix offline network migration for sqlalchemy 1.4+

Browse Source 
Sqlalchemy 1.4 dropped support for RowProxy and Row now behaves like a
tuple. This causes row and column iteration to fail using the RowProxy
semantics as the iteration methods are no longer there. Fix this by
checking which method needs to be used. This is necessary for backwards
compatibility with the Xena release for the Yoga branch.
