Upgrade feature and git to upgrade the core code - love it.
Room for Improvement:
Needs to be better documented especially the database schema.
Use of Solution:
Just stale data which can be hard to troubleshoot.

Just staff and hardware resources + maintaining and improving the application.
Well worth looking into as a CMS though Canvas is starting to pick up a lot of steam (paid though).
