Cannot connect after migrating old data

schooltool server has not started for some reason. See /var/log/schooltool/paste.log (and error.log) and look for errors or exceptions at the end, paste them here.

The problem seems to be resulting from a difference in the expecte format of the database. Is there a conversion tool that I can use to update the older database to the newer format? I couldn't import the excel file exported from the earlier version of schooltool either. I don't have intermediate versions of schooltool any more to attempt a stepwise upgrade of the database.

Here are the logs you requested from my latest attempt to connect:
