Upgrading from PTMP8 to PT11 Question

[mmtm]

Back in 2008 I bought a copy of Pro Tools 8 M-Powered. I rarely used it and moved to another DAW. I now need to get Pro Tools back on my system, and want to cross/upgrade to version 11. I have my iLok with licenses for PT 7.3 and 8 on it (along with all my plugins), but I no longer have any of the packaging or disks for them, nor do I have any idea what my Avid (Digidesign at the time) account login was/is that I used to register PT. I have a new Avid account, but it obviously doesn't have my version 7.3/8 Pro Tools registered to it.

My question is, if I purchase the upgrade from 8MP to 11, will just having my iLok with the 8MP license on it be enough to get 11 running? I don't want to make a $399 purchase only to be SOL because I no longer have any clue how to access that old Digi/Avid account.

Any and all help with figuring this out is greatly appreciated. I need to get PT up and running ASAP. Cheers!
