## Successful SAP HANA migration for global telecom company

##### The background

A global Swedish telecom company needed help managing a large SAP HANA migration project and trusted Implema Business Solution to make it happen. The two-year project involved delivering a full migration from systems on Oracle database to SAP HANA In-Memory database for 12 large SAP installations at the customer. The HANA project covered all aspects of a migration project, from proof of concept to actual migration over an intense weekend when the project had 48 hours to get everything in place.

##### The mission

Impelmas' contribution to the project was to lead the work forward in the project manager role according to agreed toll-gates, keep good communication with relevant stakeholders from the IT and business side, and monitor and follow up with the external supplier. The project was successful and the customer now has a fast database platform that gives them great future opportunities.
