I need to move stuff out of Malasaña into Millenium
|
|
|
|
## Migration notes
|
|
|
|
### Starting state
|
|
|
|
I have saved a copy of the wallet before starting the migration so that it can be used as a reference. If used offline, it allows to see what the wallet looked like before moving stuff around.
|
|
|
|
State of accounts before moving:
|
|
- malasana account: 0.21229922 btc 4 utxos
|
|
- arbret account: 0.21874886 btc 7 utxos
|
|
- MarmasPickaxes: 0.07235574 btc 6 utxos
|
|
|
|
### Plan
|
|
|
|
- Use the plain account in millenium
|
|
- Pack utxos using jittery, multiples of 2 amounts
|
|
- List transactions here
|
|
- Backup the old wallets
|
|
|
|
|
|
Exact UTXO mappings and amounts are in mappings.xlsx
