How to stop the NIMS Windows service
Stop the Windows service for NIMS that is running on the primary NIMS system. If you use a secondary NIMS (failover or redundant), the secondary NIMS system can continue operating at this time.
Do not uninstall NIMS. Many of your settings and configuration details will be migrated to OMS by keeping NIMS installed. This part of the migration only requires you turn off the NIMS Windows service to avoid any issue. This is a precautionary step.
To stop the NIMS service running in Windows:
1. In Windows, choose Start > Control Panel > System and Security > Administrative Tools > Services.
2. Select Network Instruments Management Server Service and choose to Stop the service.
The NIMS Windows service of the primary NIMS system has stopped. You are ready to install OMS.
