Nvidia Onyx to Cumulus migration and Cumulus upgrade.
Prepared MoP for seamless with zero downtime migration strategy.
Converted Onyx and old Cumulus configurations to Cumulus new version using Python script and manual edit.
PoC and tests on Nvidia Air simulation environment before migration.
It was well planned and we could work in parallel with our plan. Zero outage was happened with same-time switchover of MLAG peers.
