A few services have been developed for 3 years with goal to supplement it one day: NavigationService, DescriptionService and PageService . They have all been developed to fix a particular issue with DataStorage (performance or scalability). So a few things were still managed by the DataStorage : sites and layouts.

>>> Step2: new services have been created to replace to finish this replacement : SiteService for managing sites (similar to PageService) and LayoutService that takes care of loading the layout of a page or a site. (consider a layout as an attachment of a navigation node or a page). Those services have been implemented with existing MOP and the goal was to make nearly all existing module pass. Only tests for dashboard do not pass because the dashboard impl is a hack that should not survive a long time (but persistence is very fine). The SiteService is quite trivial (pretty much like PageService). The LayoutService was also trivial because of the reuse of the Step 1 (which is a **big** win).
>>>
>>> Step3: all the NG services have been decoupled from MOP introducing an abstraction layer (SitePersistence for SiteService, PagePersistence for PageService, etc…). At this point the NG services tests are decoupled too.
>>>
>>> Step4: code an in memory store for ram storage .

>>> Step5: reimplement the NG services using the in memory store and validate it with the tests decoupled from Step 3.
>>>
>>> Step6: now there is still some work on the import of data. It must be decoupled from the UserPortalConfigService because it is legacy and nearly fix it. The import code was decoupled from the NewPortalConfigListener (a component plugin of UserPortalConfigService). Then a new class wrapping this has been created for importing data.
