Describe the bug

I have an extra column on v3's strapi_permission table. At the moment I'm not sure if it's being used by the lib or the project. What would be the best way to port it to v4.

I get this error when trying to migrate SQL data, v3 to v4:

column "fields" of relation "admin_permissions" does not exist

Steps to reproduce the behavior

1.Follow the instruction from README file
2. See errors

Expected behavior

Not to have this error because afaik there isn't any fields column in v4's admin_permissions table.

In your database, write a query that either drops the fields column in v3 or adds a fields column in v4

Indeed, this looks like a customization that won't be covered by these scripts as it looks like you modified your admin permissions that we don't have normally.

If you aren't actively using this, you should drop it.

Reopening because @PaulBratslavsky just hit the same issue and is sending me over his test project and test database.
