Once migrated there is no connection between the previous sub-accounts and the master account. Each sub-account and the master account can be regarded as individual and separate for the purposes of the exercise. In each case all you have to do is go to http://me.com/move and follow the instructions, and it doesn't matter what order you do it in.
It’s wiser – and safer – to migrate your MobileMe sub-accounts first and your main MobileMe account last.
I did, and Apple itself now advises it.
The reasoning behind this is that if you migrate your main account first, from MobileMe to iCloud, that main account ceases to be a MobileMe account.  It becomes an iCloud account, instead.  And iCloud accounts can’t have sub-accounts.
In consequence, your MobileMe sub-accounts cease to be “sub-accounts of an existing MobileMe account” and their continued existence thus loses its former status and validity.  This threatens their own survival, orphaned and cast adrift in the electronic primordial soup.
So, it’s best to migrate them to iCloud first - whereupon they become fully-fledged individual iCloud accounts in their own right - while your main MobileMe account that has been sustaining them is still extant.  Then migrate your main MobileMe account as the final step, once your former sub-accounts are safely up and running as new iCloud accounts. There is otherwise the danger of a potential miscarriage during the migration of the sub-accounts and you could lose their names forever.
I had one main account, with my five permitted aliases and with two sub-accounts.
By following the procedure above, this became three iCloud accounts (each of which was given its own Apple ID during the transition) and my five aliases survive on the iCloud account that was formerly my main MobileMe account.
(All my MobileMe email addresses enjoyed the “@mac.com” domain name as well as the “@me.com” domain name and this survived the transition to iCloud, too.)
My credit card details appear only on the Apple ID that was formerly my main MobileMe account; they were not added automatically to the two new Apple IDs that were created when I migrated my sub-accounts to iCloud.  You’ll have to do that manually, if you want this facility, before you try to buy anything with them!
Note that the only way you can still have five aliases on an iCloud account is if you already had them when you migrated it from MobileMe to iCloud.  Normally, you can have only three aliases on an iCloud account.  So, if you want to create a new alias on your iCloud account, you will have to delete three of your existing ones (reducing you to two) in order to make room for it.
The new iCloud accounts created by migrating your MobileMe sub-accounts to iCloud can each now have three aliases of their own but they all have to be completely new ones; you can’t transfer to them any of the five from your former MobileMe main account.
Nor can you convert an iCloud alias into a full iCloud account.
And your iDisc is no more - with no substitute on iCloud.
So, you can now no longer synch files between your Macs unless, bizarrely, you also have an iPhone, an iPad or an iPod running iOS iWork linked to your iCloud account as well.  Amazingly, it’s been like that for a year.
Hutber’s Law seems to apply generally to iCloud.
(And to Lion, too, so far as I’m concerned. I much prefer Snow Leopard.)
So, think “Onwards and downwards!” when you embark on this one. 
Above all, be extremely careful with your migrations from MobileMe to iCloud: allow yourself plenty of time to perform them, don’t make any assumptions, don’t do anything without first thinking through the potential consequences of your action and don’t allow yourself to get flustered into making an error that could lose you one of your precious email addresses forever.  (Which some people clearly have.)
