I've GIT repo in Azure DevOps used in my pipelines.
This repo contains three branchs --> master (useless), PreProd and Prod
In pipeline I working on PreProd branch and after deployment I want to perform a task which merging the latest code in PreProd branch into a new commit in Prod.
So, is that possible and how?
Thanks in advance.
You could try API as @Tomasz suggested, or invoke git command to merge branches.
In addition, you could try Create Pull Request task to create a Pull Request and set Auto Complete:

If for some reason GitMerge task is not working for you, try calling Azure DevOps API for Git operations directly from script.
