I´m trying to make a parachain runtime upgrade without a migration, as a way to understand the process before trying with a migration.
I´m using version 0.9.40 of polkadot for the relay chain and the parachain template with the same version.
As I understand the process it should be as follow:
To make the upgrade in the parachain as in a solo chain, as explained here: https://docs.substrate.io/tutorials/build-a-blockchain/upgrade-a-running-network/
Then notify the relay chain of the upgrade via a priviledged transaction.
Is this correct?
I have seen other similar questions here but with a different extrinsic to be called, for example here: What is the proper way of executing a runtime upgrade on a parachain? . AuthorizeUpgrade from parachainSystem is being called. I didn´t found something similar in the relay chain. What I have encountered that seems to be similar is: ForceScheduleCodeUpgrade from paras
In case I should use that, I don´t know how to get relayParentNumber to make the call.
Any help would be appreciated.
