I'm new to tge release pipeline concept in Azure DevOps, we have four environments(Dev,QA,UAT,Prod) and the idea is once code changes are done then we need to trigger the dev stage manually and once it successfully runs then the code will automatically need to trigger other higher environments through approval, How do I need to design this through release pipelines.
As well I m having 5 build pipeline can I trigger these 5 build in single release pipeline
Please give idea to do the task
Thanks in advance
