CMDS2 – Meraki / Catalyst Migration Platform

With the changes to the Meraki platform and Catalyst integration, this is Version 2 of CMDS, designed to migrate switches leveraging Service Meraki Connect within IOS-XE packaging.

CMDS2 enables automated onboarding of:

• C9200
• C9300
• C9500

Supports:

• Single switch deployments
• Stack deployments
• Keeping IOS-XE intact (device local mode)
• Replacing IOS-XE with Meraki CS code (cloud mode)

CMDS2 Functions

Switch Migration

Supports migration from:

• Config source device
• Config source cloud

---

Network Discovery

• Scan networks automatically
• Specify IP address lists manually

---

IOS-XE Firmware Management
