We have Oracle 10g (64 bit) 10.2.0.5 on Windows Server 2008 Enterprise SP2, and we are planning to migrate our geodatabase from 9.3 to 10.3. 
       As per Esri "Oracle database requirements for ArcGIS 10.3.x" the maximim OS 
       is SP1. 

       Any one know what is limitation/risk.impacts if we keep our OS SP2 not SP1 and migrate our geodatabase?
