Can I restore text messages from my Galaxy S5 to my Galaxy 6?

[AC Question]

I recently had a Samsung Galaxy S5 and sold it after I bought the S6 Edge. I backed up my phone to my Gmail and I believe my Samsung account. But the Galaxy S6 doesn't have the same Samsung app. Now I need my old text messages from that phone. Where would my text messages go when I back up my phone? Would my Samsung account have them? How do I retrieve them from there or wherever it's stored when I back it up?
