# Upgrading Guide
### Migration scripts
There is in the project a `scripts` folder that contains `SQL` files responsible to migrate data from the database.
This script should be used if you already have an indexed database with a large amount of data.
#### `address_current_token_balances_in_batches.sql`
Is responsible to populate a new table using the `token_balances` table information.
#### `internal_transaction_update_in_batches.sql`
Is responsible to migrate data from the `transactions` table to the `internal_transactions` one in order to improve the application listing performance;
#### `transaction_update_in_baches.sql`
Parity call traces contain the input, but it was not put in the internal_transactions_params.
Enforce input and call_type being non-NULL for calls in new constraints on internal_transactions.
