I think I have some problem.
My address is 9hWttyc1RSwY8FHG6BfTYAwTgphDqxtJyv and I had 7273.916572 NRS.
In the previous NRS, I type dumpprivkey 9hWttyc1RSwY8FHG6BfTYAwTgphDqxtJyv and I got
Private key for address 9hWttyc1RSwY8FHG6BfTYAwTgphDqxtJyv is not known (code -4)
Can you help me?
You shouldn't have to dump any keys to switch to the new NRS chain. Just use your old wallet file as though it were the wallet for the new chain. (Be sure to back it up first, though.)
