Legacy system migrations are important when selecting a new content services platform. Using the example of an Alfresco legacy system, we show how content and metadata are migrated to Doxis and how content analytics support sanity checks and discrepancies requiring further action. All other content is intelligently filed in the respective folders and made available in Doxis. To intelligently import documents from a file system, Doxis first analyzes and automatically clusters them. Once completed, the result set is exported and can be used for future Doxis classification projects. This way, all imported documents are consistently migrated to Doxis.
