On the order of the number of payments to, through, and from SN, custodial and not. Probably 10s of millions of rows migrated roughly.

The hardest part is we're going from low detail to high detail and that we need to not destroy information in process despite some of the data being mostly historical at this point. e.g. referrals used to earn you a portion of a stacker's zaps, so every time they were zapped we gave you money. or, at one point 50% of a sybil fee went to rewards and the other 50% went to the territory founder. I'm having to find analogous representations of these things in the new schema or add defunct stuff to it.
