It is common to want to be absolutely sure any runtime upgrades and some mission critical extrinsics will work as expected in a safe but otherwise identical environment to a production chain. Testing this locally would be ideal.

Is there a recommended way to emulate the configuration and/or the present state, for polkadot-launch for a live relay chain?

Fork off Relay Chain

This script allows bootstrapping a new substrate chain with the current state of a live chain. Using this, you can create a fork of Polkadot, Kusama and other substrate chain for development purposes.

Also useful:

  • xcm-emulator - the emulator that takes into account state of a target chain (simulator is now in Polkadot itself).
