-# Update Procedure
-
-- Enable maintenance mode
-- [Collect migration data using ChainQL](#stakers-data-loading)
-- ❗️❗️❗️ Initiate the runtime upgrade only at this point ❗️❗️❗️
-- Wait for the upgrade to complete
-- [Execute offchain migration](#execute-offchain-migration)
-- Disable maintenance mode
-
-## Stakers Data Loading
-
-Set the environment variable (WS_RPC). For example, ws://localhost:9944. Execute the following command:
-
-```sh
-chainql --tla-str=chainUrl=<WS_RPC> stakersParser.jsonnet > output.json
-```
-
-where `<WS_RPC>` - is the network address.
-
-Example for Opal:
-
-```sh
-chainql --tla-str=chainUrl=wss://eu-ws-opal.unique.network:443 stakersParser.jsonnet > output.json
-```
-
-To install chainql, execute the following command:
-
-```sh
-cargo install chainql
-```
-
-## Execute offchain migration
-
-To run, you need to set an environment variables:
-- `SUPERUSER_SEED` – the sudo key seed.
-- `WS_RPC` – the network address
-
-Run the migration by executing the following command:
-
-```sh
-npx ts-node --esm executeMigration.ts
-```
