Cloud Manager deployment appears stuck during NIMU upgrade in Adobe Experience Manager

Last update: October 25, 2026

This article explains why a deployment in Adobe Experience Manager Cloud Manager appears to be stuck or running indefinitely when it is actually waiting for a Non-Interruptive Maintenance Upgrade (NIMU) to complete, and provides guidance on how to identify this situation.

Description description

Environment

Adobe Experience Manager (AEM) Cloud Manager (all versions)

Symptoms

  • When running a deployment through Adobe Experience Manager Cloud Manager, the deployment pipeline pauses at the wait-for-env-ready step if a Non-Interruptive Maintenance Upgrade (NIMU) is in progress on the target environment.
  • During this time, Cloud Manager displays the deployment as running, but doesn’t provide a specific status or notification indicating that it is waiting for a NIMU or other scheduled maintenance.
  • This makes it difficult to distinguish between a deployment that is paused for maintenance and one that is stuck or failing for other reasons.

Resolution resolution

Follow the steps below to resolve the issue:

  1. If your deployment appears to be stuck at the wait-for-env-ready step, and there’s no error message, consider the possibility that a NIMU or other scheduled maintenance is in progress on the environment.
  2. Check your organization’s internal communication channels or maintenance schedules for any planned NIMU activities that may affect your environment.
  3. If you don’t have access to this information or are unsure, contact Adobe Support or your Adobe representative to confirm whether a NIMU or other maintenance activity is currently in progress.
  4. Once the NIMU completes, the deployment should automatically resume and proceed to the next step.
  5. After the deployment completes, verify that the changes have been applied as expected.
