This guide aims to simplify the migration process to Cadence 1.0, making it accessible and straightforward for developers at all skill levels.
What is Cadence 1.0?​
Cadence 1.0 is the latest version of the Cadence smart contract programming language. The stable release of Cadence 1.0 represents a significant milestone in the language’s maturity, delivering a comprehensive suite of improvements that increase speed, security and efficiency. With Cadence 1.0, developers gain access to over 20 new features and enhancements. Each change is thoughtfully designed to streamline workflows, reduce duplication and improve code readability, making writing and understanding smart contracts much easier.
Staging a contract​
In order to migrate your updated smart contract to Cadence 1.0, it's crucial to stage it on the Testnet network. This preliminary step not only verifies the contract's compatibility and syntactical correctness but also ensures a seamless transition to the new environment.
_10flow migrate stage-contract HelloWorld --network=testnet
Ensure that HelloWorld accurately reflects the name of your contract as specified in your flow.json configuration file.
Confirm the contract has been staged​
To confirm that your contract is ready for migration and has been successfully staged, execute the following command:
_10flow migrate is-staged HelloWorld --network=testnet
A response of true indicates that your contract has been approved by the Flow Blockchain Testnet network and is ready for the migration process.
