Migrating to older version of Nebraska.
When migrating down to an older version of Nebraska one might have to rollback database migrations that were applied as a part of the release.
First get the migrations that were part of the version that you want to downgrade to using the following command.
:./backend/pkg/api/db/migrations | tail -n1
For example to find the migrations that were part of
2.4.0 release clone the Nebraska repo and run.
git show 2.4.0:../backend/pkg/api/db/migrations | tail -n1
To rollback to 0013_add_stats_indexes.sql use the following command
/nebraska/nebraska –rollback-db-to 0013
