Odaily Planet Daily News According to official news, IOTA has launched an old version migration tool that supports Stardust. The IOTA old version migration tool is an independent application that helps users migrate their tokens from the old IOTA network to the Stardust version. As with previous migrations within the Firefly wallet, the new tool allows users to migrate from 81-character seeds, Trinity seed library files, or Ledger devices. After a successful migration, users must use a trusted wallet and import a new mnemonic phrase, Stronghold or Ledger device.
