Up/crossgrade options

Hi guys, I'm looking at getting PT10/11 as a crossgrade.

I have MP9 ( I know that can be upgraded)

I also have m-powered essential ( dont think that can be upgraded) ?

but I also have an LE 7 in my account. I don't have the hardware anymore so I'm not sure if just the 7.3 LE amnesty Authorisation code would allow an upgrade....any ideas if that is eligible?

Any help would be great, ps I did email avid but didn't really get a straight reply.
