+## Syncing Changes Between Mainline and Flexible Environment
+
+When working with a flexible environment alongside your mainline environments, it's important to keep them aligned to avoid conflicts and ensure consistent deployments.
+
+If any changes have been made in a mainline environment those changes must be pulled into the flexible environment before pushing updates back. The changes can be updated Document Types, content, or other schema changes.

+
+If what you've been working on in the flexible environment has also been changed in the mainline, a merge conflict will occur. These conflicts need to be resolved before you can continue with the deployment. For information on how to resolve them, see the [Merge Conflicts on Flexible Environments](../troubleshooting/deployments/merge-conflicts-on-flexible-environments.md) article.
+
+Once you’ve completed your feature or update in the flexible environment and it’s synced with the latest mainline changes:
+
+* Push your changes from the flexible environment to the mainline environment.
+* From there, the changes become part of the regular deployment flow.
