A Switzerland-wide client migration of 2,500 machines during live operations
Around 2,500 machines were to be migrated to a new operating system across Switzerland, some with hardware replacement – with no noticeable downtime and no data loss. The internal attempt had failed on time, know-how and lack of user cooperation; the external team was initially seen as the 'enemy'.
Successful completion including handover to operations. High client satisfaction led to several follow-on projects.
