Overview | Getting Started with Dell OpenManage Network Manager

Generally, base the minimum configuration of any system on its expected peak load. Your

installation should spend 95% of its time idle and 5% of its time trying to keep pace with the

resource demands.

Upgrading from a Previous Version

When you upgrade your OpenManage Network Manager installation from a previous version, keep

the following in mind:

• Upgrading requires a new license to activate new features.

• Performance capabilities have been completely reconfigured. When upgrading from previous

versions, you must (re-)create dashboards from scratch.

• The following require manual migration (export, then import) from previous versions: SMTP

settings. Some scheduled items.

• You must re-create topologies as Visualizations. (suggestion: take a screenshot)

• Group Operations have been deprecated, replaced by Adaptive CLIs.

• Command monitors must be recreated, and monitors must be re-configured to monitor

Adaptive CLIs that run external scripts.

• User Names / Passwords, and User Groups (Roles) are not automatically reassigned and must

be created manually.
