We need to migrate all parachains and relay chain to state version 1. There is a pallet for doing this. With 1.0.0 Kusama will enable the state migration. After that we also need to migrate the parachains and Polkadot and its parachains. This issue works as a tracking issue.

• Polkadot [x], [x], [ ]
  • Asset-Hub [ ], [ ], [ ]
  • Bridge-Hub [ ], [ ], [ ], [ ]
  • Collectives [ ], [ ], [ ]
• Kusama [x], [x], [x]

  • Coretime [ ], [ ], [ ], [ ]
  • Encointer [ ], [ ], [ ]
  • Glutton [ ], [ ], [ ], [ ]

Three check marks: migration deployed, RPC reports done, migration removed from the runtime.
