-dbt Cloud now has two distinct job types: [deploy jobs](/docs/deploy/deploy-jobs) for building production data assets, and [CI jobs](/docs/deploy/ci-jobs) for checking code changes. These jobs perform fundamentally different tasks so dbt Labs improved the setup experience with better defaults for each. 
+dbt Cloud now has two distinct job types: [deploy jobs](/docs/deploy/deploy-jobs) for building production data assets, and [continuous integration (CI) jobs](/docs/deploy/ci-jobs) for checking code changes. These jobs perform fundamentally different tasks so dbt Labs improved the setup experience with better defaults for each. 
 
 With two types of jobs, instead of one generic type, we can better guide you through the setup flow. Best practices are built into the default settings so you can go from curious to being set up in seconds.

-And, we now have more efficient state comparisons on CI checks: never waste a build or test on code that hasn’t been changed. We now diff between the Git PR code and what’s running in production more efficiently with the introduction of deferral to an environment versus a job. To learn more, refer to [Continuous integration in dbt Cloud](/docs/deploy/continuous-integration) and [Get started with continuous integration tests](/guides/orchestration/set-up-ci/overview).

 ## What you need to update
 
-If you previously set up a job using the [Create Job](/dbt-cloud/api-v2#/operations/Create%20Job) API endpoint before September 11, 2023, you must re-create the job as described in [Trigger a CI job with the API](/docs/deploy/ci-jobs#trigger-a-ci-job-with-the-api). This is because you must set the `job_type` to be `ci`. 
+- If you want to set up a CI environment for your jobs, dbt Labs recommends that you create your CI job in a dedicated [deployment environment](/docs/deploy/deploy-environments#create-a-deployment-environment) that's connected to a staging database. To learn more about these environment best practices, refer to the guide [Get started with continuous integration tests](/guides/orchestration/set-up-ci/overview). 
+
+- If you had set up a CI job before October 2, 2023, the job might've been misclassified as a deploy job with this update. Below describes how to fix the job type:
+
+    If you used the [Create Job](/dbt-cloud/api-v2#/operations/Create%20Job) API endpoint but didn't set `"triggers":triggers.git_provider_webhook`, the job was misclassified as a deploy job and you must re-create it as described in [Trigger a CI job with the API](/docs/deploy/ci-jobs#trigger-a-ci-job-with-the-api).
+
+    If you used the dbt Cloud UI but didn't enable the **Run on Pull Requests** option that was in the **Continuous Integration** (CI) tab, the job was misclassified as a deploy job and you must re-create it as described in [Set up CI jobs](/docs/deploy/ci-jobs#set-up-ci-jobs).
+
+    To check for the job type, review your CI jobs in dbt Cloud's [Run History](/docs/deploy/run-visibility#run-history) and check for the **CI Job** tag below the job name. If it doesn't have this tag, it was misclassified and you need to re-create the job.
