Everything points to the fact that the WhatsApp Tri-Crypt Android app could be used to conversion various old versions of WhatsApp archives, which makes it perhaps your best option how to achieve crypt7 to crypt8 if something like this is even possible. It seems that the reliable thing to do would be to convert it to the original .crypt file instead.
