1. CATNIX summarized the migration of its peering platform over 20 years from 1999 to 2022, increasing bandwidth capacity from 256 kbps to 100 Gbps. 2. The recent migration in 2021 involved upgrading switches to increase switching capacity and port speeds while eliminating oversubscription and adding deep buffers. 3. The migration process took place in stages, including preparing new cabling, testing in a lab, migrating services equipment port-by-port, and configuring EVPN VXLAN and ECMP routing between the new switches. 4. A potential "horror story" was avoided when equipment was accidentally reset in the lab, but configuration backups saved the migration plan.
