Migration from Rpi1 -> Rpi2

[Skywatch]

I restored the only rpi1 image to a micro SD card using laptop and adaptor to full SD card size.
When the restore was complete I did.....
I edited /boot/cmdline.txt to boot from the sd card.
I ejected the uSD card and placed it in Rpi1 (with uSD to SD card adaptor).
I powered the Rpi1 and get the splash screen.
I get message about resizing card, setting up fs, but it gets to a point where the spash screen just says 'loading' with a bar graph slowly progressing across the screen.
When the bar graph reached the fullest extent it just sits there.
The network lights are working on the pi, but no http or ssh access.
