I work at a printing company and we get files from hundreds of different clients. Our preflight person that starts every job want to open every job in CC and use CC regardless of what version it was created in. I think this is a bad practice and we should use the version the customer used. If it were created in CS5 on the PC it should be done there not in CC on the mac just because it can. I have seen to many case where things have just not flowed exactly the same when changing versions, platforms, or font types. What are your thoughts on this. If a customer sends a Mac job done using CS5 and Helvetica Type 1 fonts should we be doing it in CC with Helvetica open type fonts?
It's best practice to use the same version of InDesign and the same fonts.
You are 100% correct.
It's probably OK to switch platforms if the fonts are all OT or Windows format TT if you can't work with the same OS, but switching versions is a disaster waiting to happen.
