HPI Config Updates
When migrating an existing HPI application from 2.2 to 2.3, it is recommended to backup your existing /hpi/configs
folder, delete the configs and re-configure HPI. While it may be possible to update existing configs, it's most likely faster to reconfigure HPI.
In HPI 2.3, Form Config was introduced into HPI, which changes the way HPI configures forms in the application. This is a big change from previous HPI releases, but makes HPI much more flexible. As mentioned in previous upgrade notes, HPI 2.3 also introduces the concept of one ObjectTypeConfig per HPI installation.
