Project import/export to use new PostgreSQL architecture
About
The Project import/exporter currently works with the existing Design Management modelling and PostgreSQL architecture.
We need to update it to work with the new modelling and architecture.
This will require a version bump to the project import/exporter because earlier imports will no longer be compatible.
Note This issue should ideally be released within the same version as #213760. This will ensure that any design management project data exported after the version bump is in the new architecture.
Issue was refined in #240691 (closed).
Permissions and Security
None.
Documentation
None.
Availability & Testing
Update a lot of existing tests of project import/export.
