Help, please help. Apple Configuratior + Profile Manger + VPP + Apple ID = **** on earth...

Hello there,

So I have inhereted a rather botched iPad rollout.

Here is what I have pieced together so far.

VPP codes are all jacked up. Some got redeemed from a master account, some from "cart specific" accounts. I am having a bear of a time, just ensuring I can correctly deploy software.

Configurator can retrieve codes if I unsupervise, but are not consistently redeploying them, likely because as I inhereted it, I made assumption to it's configuration which were not accurate.

Profile manager is pre-staged with all device serial numbers, and auto-enrollment does work correctly (yay progress)

So, here is what I have questions on.

Apple ID's for a cart of 30, do I need 3 seperate apple IDs, due to the limitation of 10 iOS devices per Apple ID?

VPP Codes, do I now need to purchase and manage my carts/codes in groups of 10, due to the above mentioned iOS limitations with concurrent devices attached to an Apple ID?

future proofing.

We are hoping to go airwatch *next year*. I wanted to do a hybrid profile manager/configurator solution. Initial deployment all thru configurator, permissions managed split between configurator and profile manager. Future free apps to be deployed via profile manager, and free apps deployed via configurator.

I need to know the logistics, not necessarily a step by step of click here, click there.

How many Apple ID's per cart, and how do I realistically manage those apps once I have the accounts provisioned. I have the basic mechanics of configurator/profile manager down. I am afraid of missing some important detail, and not being any further off than the last guy was.

Thanks in advance!
