How to transfer a huge sum of money, say $50K from a bank to another bank?

1. Add as local payee of the other bank.
2. Wait for up to 24 hours before funds transfer function is available.
3. Do a test transfer of $1.
4. Check if the other bank account has received the transfer.
5. Continue in batches of fund transfer (if needed to), for the remaining sum.

Certain banks may take up to 24hrs for the transfer limit to be processed, so take note for that!
