Complex MIgration & Upgrades 

How Zanaris Can Help You…

Turnkey migrations and upgrades are performed by professionals who have a depth of experience in multiple migration and complex upgrade scenarios, eliminating the risk of attempting tasks for the first time in a live environment. Comprehensive runbooks are provided to run step-by-step through the migration or complex upgrade with full project management.

Migrations and complex upgrades often involve refactoring at the infrastructure level to achieve the same resilience with the same or better resulting availability SLA’s. Zanaris can help assist in evaluating the best migration strategy.
