Whereas just a few years ago a system could be used for a longer period of time, things look very different nowadays. Due to digitization and the constant adjustments on the technology market, it is inevitable for companies to adapt their systems and processes to the current conditions and innovations at any time.

This requires efficient B2B integration so that productive operations are restricted as little as possible. For this purpose, an integration service provider offering powerful connectivity solutions must be engaged. The brownfield approach is usually chosen for ERP migration projects because, unlike the greenfield approach, which requires a completely new implementation, existing processes can be transferred to the new ERP system.
