In AC1, it was relatively easy to wipe devices by restoring from a backup. The iPads would get wiped, apps pushed back out over USB, and the devices renamed. AC1 had no trouble remembering whatever name had been previously assigned to the iPad, and re-applying that name during the restore process. The renaming part is one of the areas where AC2 seems to fail. It's like it forgets device names during the restore. This is very bad when you want the device name to match the uniquely numbered name printed on the device itself.
The biggest problem with the continued use of AC1 exclusively for the deployment of the iPads is that it does not support the ability to skip all of the "Welcome steps" of iOS9+ (the Setup Assistant), and there are a lot of steps now. Following a restore, it is necessary to manually skip through the steps of not setting a passcode, region, location services, and more. You have to do this on every iPad, so it is not realistic to continue using AC1 exclusively for managing the iPads.
Aside from the renaming problem in AC2, there seems to be a major problem with app deployment. First, the new app deployment mechanism in AC2 does not use the old method of downloading apps via iTunes and importing the .app file; it requires you to use "Managed Distribution" for all of your apps whether they are paid or free. If you want to deploy apps over USB during the restore process, you have to give AC2 the VPP Apple ID. When I did this, it reported that it was going to revoke the authority of PM to manage distribution of apps! I am assuming that this also means I would only be able to use this single computer to manage our apps, which is not possible across multiple sites.
The final piece that AC2 seems to break is that all of our iPads end up in the wrong timezone (and thus show the wrong time). I think restoring from a backup may deal with this, but I'm not sure.
It seems to be lose-lose, but it's not.
Note: For the following method, you must still have AC1 installed, or be able to install it. I'm not sure if you can still download it, but we still had it installed on our computer used to manage the iPads.
When you need to wipe a shared device (or devices), follow these steps.
Run AC2 and connect all of the devices. Apply a blueprint that Prepares the iPads and applies profiles. The Prepare options are where you can disable the various iOS Welcom Screen (Setup Assistant) options. It will warn you that the connected devices are going to be erased. Just tell it to go ahead.
Once the process completes (takes about an hour for us), quit AC2 and run AC1. Select the iPads you have just restored and click Refresh. AC1 will push out any apps and profiles that are supposed to be on the devices, and it will rename the devices with the previously defined names!
Unplug the iPads and you will find that the Welcome steps have been skipped (well, those that can be skipped), your apps have been restored, and AC1 even sets the right timezone. If you've installed the PM management profile, you can even use it to push new profiles and apps remotely from PM later.
As far as I can tell, this is the best way to manage a collection of shared iPads that need to be regularly wiped. I would love to hear from others if they have found a better way.
