Identify the need for an upgrade: This involves analyzing the current blockchain platform's limitations and identifying areas where improvements can be made.↵↵2. Develop an upgrade plan: Once the needs have been identified, a plan for the upgrade must be developed. This plan should include the technical changes required, as well as the timeline and resources needed for the upgrade process.↵↵3. Prepare the blockchain network: Before upgrading the blockchain, it's essential to ensure that the network is prepared. This involves updating the software on all nodes, ensuring that they have the necessary resources, and testing the upgrade process to ensure that it runs smoothly.↵↵4. Execute the upgrade: Once the network is prepared, the actual upgrade process can begin. This typically involves updating the blockchain's software, implementing new features, and fixing any bugs or issues that have been identified.↵↵5.
