I have a 1.6.0 netbox that is in use in production that I need to upgrade to get all the features we need for a development pipeline.
In trying to upgrade in-place I ran into many issues. So I built a new box running 2.5.12 and am trying to migrate the database over.
I was able to pg_dump and load the database cleanly. However, when running the manage.py migrate command, I get the below output

django.db.utils.DataError: value too long for type character varying(1)




In looking closer at this, it seems that the migration script might be looking for a value that doesnt actually exist because the feature had not been added.
I'm thinking I might have to run several versions of the migration script to bring this database up to this generation.
Does anyone have any thoughts or knowledge on which versions I would have to go through?

The delta between 1.6.0 and 2.5.12 represents roughly two and a half years of development, so it might be very difficult to pinpoint the exact failure. I suggest trying to upgrade to v2.0 first, and then to the current release from there.
