What action should be avoided before back promoting to lower environments?

Making untimely synchronization adjustments should be avoided before back promoting to lower environments because such actions can lead to inconsistencies in the data or configuration of the environments. Synchronization is crucial to ensure that all changes made in higher environments are accurately reflected in lower environments. If adjustments are made without proper timing or matching the current state of the environments, it could lead to complications, such as deployment failures or conflicts that might disrupt the existing processes and lead to unexpected behavior in the application.

By ensuring that synchronization adjustments are made at the right time, teams can maintain a clean, orderly deployment process that respects the integrity of both the source and target environments, thus facilitating smooth back promotions.
