Starting point

A retail group with 40 stores ran email, file servers and business applications on its own end-of-life hardware. Every store had its own configuration, updates were manual and outages cost revenue.

Solution

Scerus planned the migration to Microsoft 365 and Azure in waves per store cluster, standardised configurations with Chef Automate and set up central identity and access management. Every wave was tested in a pilot store.

Result

All 1,200 workplaces were migrated within eight months – without a single day of downtime in the stores. Operating effort dropped by around 30 percent and compliance requirements are checked automatically.

»The migration went through without a single day of downtime. Scerus planned every step transparently and brought our team along.«
