Question:

 Should I get the .iso from:

/pub/alt/iot/29/IoT/armhfp/iso


 For my RPi2?   What is the process for booting + installing?  

Would the following work:

0)??
1) Create the ISO/DVD 
2) Boot the machine off an attached USB DVD
3) Follow std install process to install to an SD in the RPi2

 OR what would be the course of action, if I should use the other Pi?
Would you recommend using a Pi2?  Or just concentrate on the RPi3B+?

Thanks
Doug
