Hi,

CMDB maturity should maintain as high. CMDB enabled with the help of Discovery, SG connectors, and managing the ASSET & CI flow and sync. If you are doing the ITSM devops module with devops, you should think about CMDB.

If you are talking about change management using other tools like - GitHUB, Azure Devops, etc then you should manage with the help of DEV OPS Change Velocity .
