- these helpers remove a lot of the duplicated code that we had when doing up/down column migrations, and provides a much shorter way of doing this in the future
no issue
- Existing and new sites should have portal button hidden by default and need explicit switch on from Admin.
- Default value for new sites has been updated, but existing sites still have old default and portal button set as true
- Migration here resets portal button setting to false for all existing sites, and they'll need to be explicitly turn it on from admin again
