Old Customers into Global Customers

I have a multistore client that I need to turn all their customers (in each store) into global customers. I also have to attached the new "House Account" account type to each of them in order to start doing store credits for them. Is there a way that I can accomplish this? Or will I need to change each one individually thru SQL as the account type field is greyed out when I go to customer info. Thanks!

Thanks Jeff!

I will definitely back up first! So if I do this at each store and then run my 401, this should sync all my stores with all of my customers? (I'm sure there will be multiples of the same customer somewhere)

The reason I'm curious is that I think I found a way around the layaway-commission issue that has been the bane of my rms installation for a while. Does purchase information follow the customer to each store? example...

• Joe Customer buys a watch with the credit on his house account...
• Put's down 25% of it in cash...agrees that he won't get the item until the whole cost is received.
• comes back the next day and has his account brought up to pay on his credit again
• Can Joe customer go to any store to pay > Tech,
