Erste Bank Czech Republic / Ceska sporitelna: M365 Migration

At Erste Bank in the Czech Republic, a complex switch from Google Workspace to Microsoft 365 took place in 15 months by January 2022.

Ceska sporitelna is the largest commercial bank in the Czech Republic.

Due to the size of the company and the complexity of the processes, the IT migration was a particular challenge that ORBIT was able to complete on time.

Based on the IT policy in Erste Group, the switch to MS 365 should be made as quickly as possible and at the same time every affected employee should be prepared for the new form of collaborative work - without interrupting day-to-day business.

Miroslav Lhotský, Head of COE Integration and Internal Services, Česká spořitelna, about our performance as your migration partner: "One of the greatest added values of ORBIT was the ability to respond to sudden changes and requirements."
