V6 Change Customer on Invoiced (& Posted) SO

After posting an invoice for a customer, we realized we had selected the
wrong customer (a different division of the customer's company).

Since certain customers/divisions are assigned to different GL accounts
than others, we can't simply overlook the mistake.

Ideally I'd like to delete the existing invoice and generate a new one,
but I don't know of a way to do that.

Does anyone have a procedure for dealing with such a circumstance? I'd
hate to have to generate an entire new sales-order for this...

Thanks.
