Bob Walker shares his experience of creating a PowerShell script to clone an Octopus Deploy project from a sample instance to Redgate's instance, emphasizing the limitations of the existing Octopus Data Migration tool and the Octopus Deploy API. The default migrator tool has several constraints, such as requiring database access and potentially overwriting custom changes, which prompted Walker to develop a script tailored to his specific needs. His script, shared on GitHub, allows selective cloning of project components and supports multiple runs without overwriting everything, focusing on simplicity and specific use cases. Walker's approach includes using dummy data for sensitive information, filtering data for cloning, and handling variables and deployment processes with care to avoid unnecessary overwrites. He highlights potential use cases for his script, such as syncing projects between different environments and breaking large spaces into smaller ones, and encourages others to fork and adapt the script for their requirements.
