Perform Updates

  1. You must update spec.json and Parity node to version 2.6.5 as the spec format was changed. This requires a slightly different update process: Use this guide to upgrade.
  2. Organize the HF on block 12095200

Verify

Once your update is complete, verify the HF block number:

grep -n -A2 12095200 spec.json

You should see:
