Rococo is testnet for Kusama and Westend is testnet for Polkadot. To prepare parachain for Kusama, we have to test our application on Rococo. Likewise, we should test our parachain on Westend before going to Polkadot.
For Rococo, there are some instructions provided here https://docs.substrate.io/tutorials/connect-relay-and-parachains/acquire-a-testnet-slot/#request-a-parachain-slot.
We have to book Rococo slot request here https://github.com/paritytech/subport/issues/new?assignees=&labels=Rococo&template=rococo.yaml
But I couldn't find specific instructions for Westend.
Is the Westend deployment process same as Rococo? Where should I give slot request for Westend? or Testing on Rococo is good enough to go for Polkadot?
Can somebody please help me to know the process for Westend deployment?
