Too much manual administration
Routine changes still mean maintaining configuration by hand.
Nagios Core → XI migration
Migrate from Nagios Core to XI—Without Starting Over
Keep the hosts, services, plugins, and monitoring logic you’ve already built. MCS helps you move to Nagios XI while Core keeps monitoring until the new environment is ready.
Core can keep working. Managing it may be the problem.
As environments grow, the burden often shifts from monitoring systems to maintaining the monitoring itself.
Reporting takes extra work
Dashboards and reporting often require additional setup and maintenance.
Growth adds complexity
More systems, users, and requirements make a manually managed environment harder to maintain.
Maintenance consumes engineering time
Core may still work—but maintaining everything yourself takes time away from other priorities.
Protect the monitoring you’ve already built
You don’t have to rebuild your monitoring from scratch.
Nagios XI can import existing Core configuration and plugins. MCS helps determine what can move directly and what needs attention before cutover.
- Keep Core monitoring while XI is built and tested
- Preserve existing hosts, services, plugins, and monitoring logic where appropriate
- Verify monitoring coverage, plugins, and notifications before cutover
- Confirm XI after cutover and address migration-related issues
