Sub0 Online: Storage Migration - Standalone chain to Parachain
Why Substrate and Polkadot Stack Exchange recommends it
Substrate Stack Exchange answerers point people to it when asked how to convert a solo chain to a parachain or carry over existing chain data, since it is a real production case study.
Recommended by 3 people across 3 different months, 2022 to 2023.
What it is
A Sub0 Online conference talk by Frederik Schulz of Centrifuge on moving a live standalone Substrate chain to a parachain. It uses Centrifuge's own migration as a case study, covering how balances, vesting locks and proxies were migrated and how the new state was verified.

You can check out this presentation which has Centrifuge's solochain to parachain migration as a case study (Sub0 Online: Storage Migration - Standalone chain to Parachain ): [this video]
Recommends Alex Bean - R0GUE · 2023-03 · Substrate and Polkadot Stack Exchange · on “how we can migrate the solochain data to the parachain?”
Check the answer to this previous question on StackExchange: Do not want to clean up the data of the independent chain, how to seamlessly connect to the parachain? [LINK] . I like to share too this video of the Sub0 conference: Sub0 Online: Storage Migration - Standalone chain to Parachain [this video] Also is not about migrate data but worth to check this tutorial in Substrate docs about how to Convert a solo chain into a parachain [LINK] .
Recommends Rodrigo Quelhas · 2023-07 · Substrate and Polkadot Stack Exchange · on “Is it possible to bootstrap a parachain node from pre-existing solo chainstate?”
Yes, it is possible. Have a look at this previous question: how we can migrate the solochain data to the parachain? [LINK] Also, have a look at this video: Sub0 Online: Storage Migration - Standalone chain to Parachain [this video]
