Accelerating network migration for global enterprise

Client profile

Large multinational company with a cloud-first strategy to migrate 850 offices globally from a legacy SD-WAN solution to their new chosen technology (Versa Networks) in a short timescale.

The challenge

Operating a single network with two SD-WAN solutions brings many operational challenges so migration timeline should be minimised. Customer requested an accelerated migration timeline covering multiple time zones and doing up to seven migrations per day to accommodate.

Client needs

Fast execution while ensuring high service levels to the business.

Our responsibilities

  • Work closely with the client, technology vendor, and its outsourced managed partner to detail a migration plan and lead the site migrations.

  • 10-day post migration operational ownership and responsibility for 24/7 support during that time.

  • Standardise and redevelop configuration templates to ensure a consistent and replicable approach for the site migrations.

  • Conduct migrations in five different languages across 5 continents.

Results achieved

  • Seamless migration with 100% first time successful migrations.

  • Leveraged automation to programmatically retrieve necessary data from the legacy SD-WAN solution's orchestrator and seamlessly provision the new solution with essential configuration options.

  • Working closely with the client’s OSS, Cavell Group developed robust monitoring processes which enabled average migration activities time to decrease by 50%.

  • Up to seven migrations per day and up to three concurrent migrations.
