Issue/Introduction

During vCenter Server pre-update checks, users may encounter the following warning message:

Warning: Files that cannot be used with Lifecycle Manager will not be copied from the source.
These files include VM guest OS patch baselines, host upgrade baselines and files, and
ESXi 6.5 and lower version host patches baselines.

Resolution: Please review VMware Lifecycle Manager Documentation for details

Please refer screenshot :

Environment

VMware vCenter Server 7.x

VMware vCenter Server 8.x

Cause

This warning appears during pre-upgrade/update checks when the system detects legacy baseline configurations and patch management files that are not compatible with the newer vSphere Lifecycle Manager (vLCM) architecture.

The warning is triggered because:

  • The upgrade process will not migrate certain legacy files
  • The system is transitioning to a new architecture for lifecycle management
  • Older baseline types are being deprecated in favor of vLCM Images

Resolution

This warning can be safely acknowledged, and the upgrade/update can proceed after taking the following precautions:

  1. Backup Preparation
    1.  Take snapshots of the vCenter Server
    2. Perform regular backup procedures according to your organization's policies

  2. Verify Environment Compatibility
    1. Ensure all managed hosts are running ESXi 7.0 or later
    2. Confirm all critical workloads are compatible with the target vCenter version

  3. Post-Upgrade Actions
    1. Plan to create new baselines using vLCM Images
    2. Begin transitioning from traditional baselines to vLCM Images
    3. Configure new driver updates through Lifecycle Manager in the vSphere client
