Thanks! That was my understanding, I was just concerned about general file compatibility across the different versions. I used the following KB for reference:
http://www.chiefarchitect.com/support/article/KB-00516/
My confusion stems from this statement inside the knowledge base article:
If you are uncertain as to whether or not your version of Chief Architect is the same version as the individual using the Home Designer program, you can use the information below as a guide.
Chief Architect X6 <=> Home Designer 2015
Chief Architect X5 <=> Home Designer 2014
Chief Architect X4 <=> Home Designer 2012
Chief Architect X3 <=> Home Designer 10
Chief Architect X2 <=> Home Designer 9
