Not without CS4 as a go between.
@kc.k – You will need InDesign CS4 for that.
CS4 is the only version, that can export/import both IDML and INX exchange formats.
And you need an exported INX file (from InDesign CS4) that can open your exported IDML file from CS6, CC or CC-2014.
Since you are still running CS3 I'd suggest you downloading a 30days version of CS4 and do the conversion:
Read the Note about downloading very well before trying !!
Ok, thank you. I appreciate the quick response!
