Uniper – Successfully decommissioning a legacy DMS to Microsoft SharePoint & a file share

Challenge

Planning to decommission their OpenText Documentum ECM system, Uniper, a global player from the energy sector, faced a big challenge. Approximately 11.5 million documents with a volume of nearly 2 terabyte of content had to be migrated. The content was spread out over 97 cabinets representing various use cases and/or business units resulting in more than 60 document types with more than 170 individual attributes. The quality assurance requirements posed another obstacle throughout the migration project as each cabinet had to go through an individual multi-step process proving the completeness and correctness after which an additional user acceptance test and a quality assurance audit had to be passed as well. Finally, the tight timeframe further increased the hurdles to a successful completion of the migration project.
