When upgrading from an earlier release of DXA to DXA 1.4 (Java) are there any changes on the CMS side or just the DXA libraries and web application? I am asking this since we have a lot of custom content types created and I am not sure how any CMS side update would affect those.
We are running SDL Tridion 2013 SP1 HR#2 with Oracle as the CM & CD database.
