When a tool like NetMRI reaches end-of-life, the immediate instinct for many network teams is to freeze. Years of configurations, compliance rules, scheduled jobs, device credentials, connection profiles, and internal routines have all been built around it. Pulling it out of the environment feels like performing open-heart surgery on a running system.

But once the initial shock fades, teams discover an important truth: migrating away from NetMRI is far less painful than it appears — provided you understand the structure of what needs to be moved and approach it in the right order.

Migrations don’t fail because the work is technically difficult. They fail because teams don’t frame the process properly. The key is to treat the migration not as a massive project but as a structured series of small, controlled, predictable steps.

Understand What You’re Actually Migrating

NetMRI did a lot of things, but its value can be reduced to a few core pillars: configuration backups, historical context, compliance policies, and basic automation. These pillars are where your migration effort should focus.

Most teams discover that the rest — dashboards, reports, charts, and secondary features — aren’t actually essential. The operational safety net that NetMRI provided came from a much smaller set of functions.

Start by breaking down your environment into three simple buckets:

1. Configuration History

This includes all the device backups collected over the years. You don’t necessarily need to import this historical data into the new system, but you do need to catalog it, archive it safely, and ensure you can reference it if needed.

2. Compliance & Policy Logic

Compliance rules, golden configs, checks, and remediation logic are often the most portable part of a migration. Most organisations have far fewer policies than they think — usually a core set related to passwords, SNMP, logging, access control, and banners.

3. Automation Tasks

These tend to be simple in NetMRI: parameterised scripts, CLI templates, scheduled jobs, and a few ad-hoc routines. These migrate best when rebuilt cleanly rather than ported directly.

Once these areas are identified, the migration becomes much easier to reason about.

Don’t Try to Migrate Everything

One of the biggest mistakes organisations make is attempting a one-for-one replication of the entire NetMRI ecosystem. The result is usually frustration. NetMRI’s architecture and workflow model are not identical to modern NCM tools, and trying to recreate its exact behaviour defeats the purpose of upgrading.

The smarter approach is to migrate intent, not implementation.

For example:

• If NetMRI ran nightly backups at 2am, the new tool should do the same — but you don’t need to move the old job definition.

• If NetMRI applied a compliance rule that checks for AAA settings, you need the rule logic — not the old UI structure it lived in.

• If NetMRI ran a template that pushed VLAN updates, rebuild that task natively rather than trying to translate the old template line-by-line.

By focusing on outcomes, teams avoid bringing legacy complexity into a new, cleaner environment.

Clean Up Before You Move

NetMRI environments, especially those running for many years, accumulate a lot of noise: stale devices, unused templates, outdated policies, and automation jobs no one remembers creating. Migration is the perfect time to prune this.

A lightweight cleanup typically involves:

• identifying unused devices

• removing duplicate or deprecated jobs

• trimming compliance policies to the ones actively used

• clearing credential entries that are no longer valid

This cleanup alone reduces migration time dramatically.

How to Move Config Backups Safely

Config backups are often the most emotionally sensitive part of the migration — they hold years of operational history, and losing them is unthinkable.

The good news: you don’t need to import them into the new tool.

It’s perfectly acceptable to:

• export them from NetMRI,

• archive them securely,

• store them in a read-only repository, and

• let the new NCM platform begin collecting fresh versions going forward.

Historical configs don’t need to sit inside the active system; they just need to be available. Engineers rarely compare configs from five years ago during day-to-day work. What matters is:

• last-known good version,

• previous known version,

• and a searchable timeline.

A clean split makes the migration faster and the ongoing system smaller and faster.

Recreating Compliance Policies

Compliance is usually the easiest part of the migration. Most rules consist of a small set of patterns or required lines, and nearly all modern NCM platforms support similar logic.

A practical technique is to rebuild policies directly from the documentation of what they enforce — not from NetMRI’s exported XML or internal definitions. This gives you a clean policy set, free of historical noise.

You may discover along the way that some policies aren’t actually used anymore. Many teams build policies for an audit and then never revisit them. Migration offers the chance to reset and remove clutter.

How to Handle Automation Workflows

Automation tends to cause the most hesitation during migration, because engineers worry about losing a heavily-used script or breaking a scheduled job that no one has touched in two years.

The reality is that NetMRI automation was intentionally basic — and that makes migration much easier. Most jobs are simple tasks: push a template, run a command, collect output, or update a setting.

When rebuilding automation in a modern NCM platform, you want to focus on:

• clarity,

• maintainability,

• and alignment with current practices.

Many teams discover that rewriting automation tasks actually improves them. Old assumptions are removed, templates become cleaner, and brittle logic is replaced with predictable workflows.

The Safe Migration Process (Minimal Bullet List)

A reliable, low-risk migration away from NetMRI usually follows this flow:

• Run the new NCM platform in parallel — begin collecting fresh backups, diffs, and change alerts.

• Verify behaviour on a subset of devices — ensure the new platform reliably accesses the network.

• Migrate compliance rules next — they are portable and easy to validate.

• Rebuild automation last — after you trust collection, compliance, and reporting.

This parallel approach avoids outages and gives the team breathing room.

Where rConfig Fits Naturally Into the Migration

rConfig tends to be adopted during this phase because its lightweight architecture makes parallel deployment simple. Teams can begin collecting backups within hours, verify diff accuracy, import compliance rules cleanly, and test automation without disturbing the existing NetMRI environment.

Migration doesn’t feel like a “project” — it feels like a transition.
That distinction matters.

Conclusion

Migrating away from NetMRI doesn’t need to be complicated or disruptive. The trick is to understand what NetMRI truly provided, preserve only what matters, and rebuild cleanly rather than dragging legacy structures into a modern platform.

The end result is almost always a more organised environment, cleaner policies, more predictable automation, and a toolset that actually matches the needs of today’s networks instead of yesterday’s.

A thoughtful migration doesn’t just replace NetMRI — it improves on it.
