Transferring texts from PC to Galaxy S6

[AC Question]

When I started having problems with my S4, I backed up my contacts, photos and text messages to my PC. The phone did eventually die, and the folks at the Verizon store were unsuccessful at reviving my phone just long enough to do a full transfer from my S4 to my newly purchased S6. I was successful migrating my backed up contacts and photos from my PC to my S6, however, cannot figure how to migrate the text messages. Any advice?
