One System
Upgrade:
- This approach is simpler.
- This approach assumes the same host as the prior version of operation.
- The repository components are upgraded in the same repository database.
- This approach is suitable, when the number of agents is less.
- Requires downtime.
- OMA , OMS and Repository database are upgraded at once.
Two System
Upgrade:
- This approach is useful in more complex monitoring environments, where:
- A different host from the prior OMS version of operation will be used.
- The repository components will be upgraded in a different repository database copy.
- Best suited for large agent counts and anywhere the unmonitored time must be minimized.
- Minimal Downtime
- The existing reports, metrics and jobs are migrated as well.
