Switch to Cloud RADIUS in Days, Not Months
Every migration gets a dedicated engineer, a parallel deployment, and a rollback plan. Your users never notice the switch.
Why RADIUS Migrations Feel Scary
We get it. Touching your authentication infrastructure is nerve-wracking. Here is what keeps most teams stuck.
Legacy Configurations
Years of accumulated RADIUS policies, dictionaries, and vendor-specific attributes that nobody fully understands anymore.
Certificate Complexity
Server certs, CA chains, client certs, SCEP profiles - one misstep and thousands of devices lose network access.
User Disruption Fear
Nobody wants to be the person who knocked 5,000 employees off WiFi because the RADIUS migration went sideways.
Policy Translation
Authorization rules, VLAN assignments, MAC filtering, group policies - every vendor does it differently.
It does not have to be this way. We have migrated hundreds of organizations with zero user-facing downtime. Here is how.
Migration Paths by Vendor
Every platform has its quirks. We have mapped the migration path for each one.
From Cisco ISE
2-4 weeksThe most complex migration we handle - ISE has deep tentacles. But we have done it many times and have the playbook down.
From Aruba ClearPass
1-3 weeksClearPass policies export cleanly. The main work is mapping enforcement profiles to IronWiFi's conditional access rules.
From Microsoft NPS
1-2 weeksNPS migrations are straightforward. Your AD integration stays - we just authenticate against it from the cloud instead of on-prem.
From FreeRADIUS
~1 weekThe fastest migration path. Your config files translate directly to IronWiFi settings - we even parse your radiusd.conf and users file.
From Other RADIUS Vendors
1-3 weeksFortiAuthenticator, Cloudpath, daloRADIUS, Portnox, or something custom? We have a generic migration path that works for any RADIUS source.
How Every Migration Works
Six steps. Zero downtime. Your legacy system stays running until you are 100% confident.
Discovery and Assessment
We audit your current RADIUS setup: policies, certificates, directory integrations, vendor attributes, and edge cases. You get a detailed migration plan with timeline.
Parallel Deployment
IronWiFi goes live alongside your existing infrastructure. Both systems run simultaneously - your current setup keeps working exactly as before.
Policy Migration
We translate your authorization rules, VLAN assignments, MAC policies, and group-based access controls into IronWiFi's configuration. Every rule is documented.
Testing and Validation
Every authentication flow is tested against the new system: EAP-TLS, PEAP, MAC auth, guest access, VLAN assignment, certificate validation - all of it.
Cutover
A DNS or IP change on your network equipment points traffic to IronWiFi. It takes effect in seconds. Users reconnect automatically without noticing.
Decommission Legacy
After a validation period (we recommend at least two weeks), safely decommission old RADIUS servers. Rollback is available the entire time.
The ROI of Moving to Cloud RADIUS
On-premise RADIUS costs more than you think when you add up servers, licensing, staff time, and outage costs.

What You Keep
Migration does not mean replacing everything. Your existing infrastructure stays in place.
Access Points and Switches
Cisco, Aruba, Meraki, Ubiquiti, Ruckus, Cambium - all work with IronWiFi. No hardware changes needed.
Existing Certificates
Import your server certificates and CA chains. Client certificates issued by your PKI continue to work without re-enrollment.
User Directories
Active Directory, Azure AD, LDAP, Okta, Google Workspace - IronWiFi authenticates against your existing identity provider.
MDM Policies
Intune, Jamf, Workspace ONE, Mosyle - your MDM device profiles and WiFi configurations stay intact with minimal updates.
Dedicated Migration Support
You are not doing this alone. Every migration gets hands-on engineering support.
Your Dedicated Migration Engineer
From discovery to decommission, one engineer owns your migration end-to-end. They know your setup, your timeline, and your constraints.
- Named engineer assigned to your account
- Weekly status calls during migration
- 24/7 escalation during cutover window
- Documented rollback plan before cutover
- Post-migration validation for 2+ weeks
Migration SLA
Every migration completes within the agreed timeline or we extend support at no extra cost.
Migration FAQ
The questions every IT team asks before making the switch.
Will there be downtime?
No. We run IronWiFi in parallel with your existing infrastructure. The cutover is a DNS or IP change that takes effect in seconds. Your users never notice.
How long does a migration take?
FreeRADIUS: about a week. Microsoft NPS: 1-2 weeks. Aruba ClearPass: 1-3 weeks. Cisco ISE: 2-4 weeks. We run in parallel the entire time.
Can we roll back?
Absolutely. Your existing RADIUS stays running until you are satisfied. Rolling back means pointing your equipment back to the old servers. We recommend keeping legacy up for at least two weeks after cutover.
Do we need new certificates?
Usually not. IronWiFi supports importing your existing server certificates and CA chains. Client certificates continue to work. If you want IronWiFi Cloud PKI, we transition gradually.
Will users need to do anything?
For most migrations, nothing. Devices reconnect automatically. If certificate changes are involved, we coordinate re-enrollment through your MDM or our enrollment portal.
What about our AD/LDAP?
Your directories stay in place. IronWiFi integrates with Active Directory, Azure AD, LDAP, Okta, and Google Workspace. We authenticate against them, not replace them.
