Warning seen in generic-snmp block while upgrading

Products

• VMware Smart Assurance

Issue/Introduction

During an upgrade of M&R from version 7.8 to 7.9, a warning is observed in the generic-snmp block logs or during the module update phase: 

Module found in '/opt/APG/Block/generic-snmp/Generic-SNMP'.

! WARNING: The configuration file 'conf/tmsconfig.xml' for module 'topology-mapping-service' has been modified and is not compatible with the new version. It has been backupup at 'conf/tmsconfig.xml-old-7.9_YYYY-MM-DD-XXXXXX.bkp

Environment

All supported releases of Watch4net|M&R

Cause

The installer detects that thetmsconfig.xmlfile was customized in the previous version (7.8). To ensure the upgrade completes, the installer replaces the customized file with a default 7.9 version and creates a backup of the original. In version 7.9, the default<host>tag intmsconfig.xmlis often set tolocalhost, whereas distributed environments may require it to point to the specific Backend (BE) host.

Resolution

To restore functionality, manually merge the customized settings from the backup file into the active configuration:

1. Navigate to the module configuration directory.
2. Locate the backup file identified in the warning (e.g., tmsconfig.xml-old-7.9_2026-03-25-132814.bkp).
3. Compare the backup file with the currenttmsconfig.xml.
4. Identify the<host>tag. If the backup shows the Backend (BE) host IP/Hostname and the new file showslocalhost, update the new file to match the backup:
    
5. Save the changes.
6. Restart the M&R services or specifically thetopology-mapping-service module.
7. Log in to the M&R Admin UI, navigate to the generic-snmp block, and perform a Reconfigure action to ensure all components are synchronized.
