In this video, Rob Hirschfeld and Greg Althaus provide operators real-world examples of how best to migrate your provisioning platform to Digital Rebar Provision. This blog highlights one of these migration ideas.

Scenario

  • 10 Servers running in multiple subnets
  • DHCP Server
  • Cobbler Provisioning Tool

Migration Process

  • Setup Digital Rebar Provision (DRP) in the Network
    • Create a new subnet with DHCP server installed
    • Operate the DHCP in reservation mode
  • Run DRP to discover the entire network across subnets without DHCP access
    • Create a mapping of infrastructure including MAC address to IP address
  • Migrate DRP control server by server
    • Turn off old DHCP server control for a specific MAC address and turn it on for new DHCP server
    • Reboot the specific MAC address node and DRP will manage the provisioning for that specific server
    • Confirm reset server and continue to manage the changeover server by server
  • Other Options
    • Continue to manage Cobbler for existing infrastructure and use DRP for all new nodes
    • Split provisioning services based on application being deployed
