Thank you for that Tod. I have the E Visa issued to my new passport however I am in China now on my old my passport and will be traveling from here to Thailand also on my old passport. I suppose when I get to Thailand I will just show them the print out of my DTV and both passports. Should be fine.
I don’t think that is entirely true. Why would there be serious problems? I could just show both my passports and immigration could clearly see that my old passport is about to run out of space so I have prepared my new passport in time for my visa. I think this is the most sensible thing to do in this situation rather than put a brand new visa in an old passport that only has a few pages left.
