Azure CI pipeline trigger not working after git instance migration - azure

I have few CI and CD pipelines in azure devOps project in which CI pipelines connect to github enterprise repository to fetch the code.
CI pipelines were invoked by the trigger whenever there is a change in main branch of repository.
This was working fine until our git repository instance was changed. All our git repositories are migrated to the new instance.
I have updated the service connection, to point to the new git instance and manually invoked CI pipelines and tested. It worked fine.
But the issue is now with automatic triggering of CI pipelines. It is not working now.
I tried remove and add git service connections and repository details inside CI pipeline and enabled trigger, but still it is not getting automatically invoked whenever there is a change in repository.
What could be the reason for this ? I already removed and added the git repository details in CI pipeline, still that does not work. Is there anything I missed out? Any leads appreciated!

You can check the "Override the YAML trigger from here" setting for the types of trigger (Continuous integration or Pull request validation) available for your repo." in the Triggers UI.
If it does not work, please create a new pipeline to check if it works.
For more information, you could refer to: troubleshooting failing triggers

Finally figured out the issue and fixed. It was error with web hook in the repository.
Updated the webhook and it is working fine now.

Deleting a data factory component not working using CI CD pipelines

I have implemented CI CD for Azure Data Factory. When I modify a pipeline and publish my changes and deploy it to UAT, the changes reflect properly. The problem arises when I delete any component in dev and publish it and deploy it to the UAT data factory. The changes do not reflect.
How to handle the delete scenario in CI CD pipelines?
As of now I am creating separate releases. Everytime they are deployed, the deleted changes are not reflecting.
CI\CD only merge changes, so it doesn't delete objects.
If you are using the Azure DevOps release pipeline, there is a Microsoft PowerShell sample script that has this ability that you can add to your release pipeline.
Explanation on how to use the script in a release pipeline - here
Link to the GitHub project containing the actual script.
Set the parameter deleteDeployment to true (like this: -deleteDeployment $true).

How to Trigger a build pipeline depends on create PR request source branch in Azure DevOps

I have a Develop branch and Master. My task is to trigger the build pipeline when I create a Pull Request from Develop to Master before merge, depends on Develop branch. The trigger should be from source branch. Can we add tags to trigger the build pipeline based on source branch. I am using classic pipelines and new to ADO. how can I achieve this. Please someone help me to achieve this in detail.
To get a pipeline to trigger when a PR is opened but before it is merged you would need to add a branch policy on master branch to have a build validation step. This will trigger the pipeline to run whenever a PR is opened to master
Build Validation
Unfortunately, PR trigger behaviour varies, depending on which SCM you're using: Azure Repos Git, GitHub, or Bitbucket Cloud. With BB Cloud, the PR build will be triggered when the PR is opened or updated, but not when it is merged. The filter input can be used to specify branches for PR trigger.
Details for each SCM system can be found by clicking on the links on the "Triggers in Azure Pipelines" documentation.
The way how to set that up does depend on your source-code version control software you are using. For GitHub you need to install the "Azure Pipeline" GitHub App.
Then configure a pipeline in AzureDev Ops and enable "Continous integration" in "Triggers" section.
P.S.: To avoid that the compile check of a PR will result in published artefacts you can either have to different pipelines or - that's what I try to achieve - one pipeline where the artefacts are just being generated when the PR is merged.

Why doesn't Azure Pipelines pick up commit on GitHub?

We use Azure Pipelines for our CI/CD processes since a few weeks. The CI pipeline gets code from GitHub, builds, tests and creates a deploy package.
From the beginning I am quite certain that every commit got detected as intended, but recently that is not the case. Manual triggers and scheduled triggers work, but continuous integration does not.
What could be the causes for this?
In the pipeline, we checked the box for "continuous integration", and we use the recommended GitHup App to provide authorization. This is verified to work, we can see the authorized GitHub repos in the pipelines settings.
You can check if the github branch you committed to is included in the Branch filters. If it is not included. Click Add to add the branch.
Check if there is skip CI command(eg.[skip ci]) in commit message. See here for more information.
If CI trigger is not working even all the settings are correct. You can try below workarounds:
1,Disable the CI trigger, save, then re-enable it and save it again.
2,Clone your build definition. See below screenshot
3, Create a new build pipeline with the same trigger and settings.
If all above arenot working. You can go to this site to see if there is a server outage of azure devops.
We ended up changing how we connect from Azure Pipelines to GitHub. The recommended way is to install the Azure App in GitHub and connect using that in Pipelines. My experience is that it worked at first, but stopped working. I read somewhere that only the first connection works with webhooks, so maybe we tried it somewhere else or something that broke it. I ended up using a GitHub servic account to pull and listen for webhooks, and that works just as expected.

Azure Repo submodule CI/CD

In my Azure repo for my function app, I included a submodule that is cloned from another Azure Repos. I try to enable CI/CD pipeline of this function, however, if I change and commit a new change to the submodule's original Azure repo, it cannot trigger a new build and deploy of the function APP. Is there a way to enable CI/CD for Azure repo submodule change?
For this issue, you need to enable the Checkout Submodules option in the advanced section of the Get Sources step.
You can refer to this document for details.

How Azure check and run updated code when push to github repository ? Does it affecting on performance?

When i push my updated Angular 2 code to Github Repository. Azure Hosted Web Application with using that git repository immediately serve updated code. Does it check every time for latest changes? If yes then is it affecting on performance? What is the Azure web app life cycle after code push to git repository ?
When you link a GitHub repository, Azure App Service registers a Webhook on GitHub. When you push to GitHub, it triggers a Webhook that then triggers a deployment of the code. The github repo is pulled (only pulling the changed files, just as if you did a git pull <branch>. It then runs the deployment script (or generates one and then runs it if you haven't supplied one). The default one does an npm install --production followed by an npm build before restarting the service.
