RE: T22 and firmware upgrade
I don't know if it possible to pass directly from a .5x firmware to a .7x. I suppose you may pass from .5x to a .6x first, then to a .7x if you want to be sure. But maybe it is possible to pass for 5 to 7... I don't know.
You may check v70 documentation to see if it says something about it.

V70 makes big changes in autoprovisioning format... You can find various documentation for infos about it at the above link.
