Migrating MobileMe family accounts to iCloud

I've started migrating family accounts to iCloud. This explanation from Apple Discussions is helpful ...

With a Family Pack, the master account holder and the sub-account holders can each migrate to an individual iCloud account by going to http://me.com/move and entering their email address and password (not www.icloud.com). The order they do this in is immaterial; if the master account moves first it can no longer administrate the sub-accounts. If a sub-account moves first the master account cannot create a new sub-account to replace it. Once migrated each account becomes a full iCloud account entirely separate from the others. The master account holder will get the 20GB storage upgrade free until June 30th 2012; the sub account holders will not, and will have only the basic 5GB.

I began with #2, currently using a SIM-less iPhone 4. He's got almost no data to lose.

I want him to continue to use my Apple ID however ...

... iPhone, iPad, and iPod touch must have iOS 5 or later. Note: When you are asked to provide your Apple ID during iOS setup, use your MobileMe email address and password. To use a different Apple ID for iTunes and iCloud, just go to Settings > Store on your iOS device after you've finished the iOS setup assistant...

... Inactive and expired MobileMe accounts do not need to move to iCloud. Simply use your inactive or expired account to sign up for an iCloud account and follow the onscreen instructions. See this article for more information...

and

When you first set up your iOS 5 device, enter the Apple ID you want to use with iCloud. If you skipped the setup assistant, sign in to Settings > iCloud and enter the Apple ID you’d like to use with iCloud.In Settings > Store, sign in with the Apple ID you want to use for store purchases (including iTunes in the Cloud and iTunes Match). You may need to sign out first to change the Apple ID.

Following this path I learned that #2 will still have MobileMe Gallery, iDisk and iWeb Publishing through 6/30/2012 -- even after moving to iCloud. Better than I'd expected. No keychain sync though. I hope that comes back in some form.

I had to enter his iCloud (same as MobileMe) credentials to setup Facetime and iMessage on his SIM-less device. Although the phone doesn't need a SIM for this, it can't be in Airplane mode.

So far, it has gone better than expected.

Update: Thinking this over, I realize I need to update my machines to Lion before I move Emily and I. So this will take a while ...
