My Azure ASM to ARM script

This is the “script” I used to move our older classic environment VMs to the new Azure Resource Manager.
It it is not a function – I wanted to step through the process and make sure all was well at the different points in the script.
The script assumes that there is only one Data disk (or none), and that you have created your availability set before hand.
I based most of the script off this.

I hope this helps some one.
