I have SDL Tridion 2011 SP1 installed. But the Delivery environment is of 2011 GA version installed on Windows 2008 R2 SP1 server. So I have hybrid version running in my system.
Now I want to upgrade to SDL Tridion 2013 completely.
I am planning to first upgrade Delivery services to 2011 SP1 version. Later I am planning to do update from 2011 SP1 to 2013.
I am not sure of the compatibility issues that I could face.
Please suggest me the precautions for this.
