2023-04-06: Lots of progress has been taking place. Migration Plan is almost complete and a draft is ready are Migration Strategy through an IPNS Key. More details on what’s left lives in Migration Strategy Details.

2023-03-20:

• The DHT Double Hashing specification is close to being finalised and the corresponding changes are being integrated into the codebase.
• This is a reasonable time to start thinking about the migration details, i.e., how we’re going to land the breaking change to production.
• We are planning to have the migration plan (i.e., not the migration itself) in place by the time of IPFS Thing (April 15-19 2023).
• This document will serve as the project doc to track progress towards the goal of defining the Migration Plan and Strategy.
