I am finally able to leave the deprecated realm of ArcGIS 10.0 and move into the modern times. The question I have is should I bother with a 10.2 installation or go to 10.3? Also, will 10.2 desktop read/write a 10.3 SDE database?
A colleague sent me this; Client and geodatabase compatibility—ArcGIS Help | ArcGIS for Desktop which answers the compatibility issue.
