Question would doing a export/import to handle the upgrade from a
python2 to python3 be acceptable or doable?

My thought is upgrading from python2 to python3 could be handled like we
do a database change. Export the tracker using the python 2 instance,
then import the data into a python3 based tracker.

For large trackers this may not be a good mechanism, but for testing
purposes I think it should work.
