Many organizations that have deployed SharePoint 2010 or 2013 also have some type of legacy ECM system in place.
However, SharePoint also has rich ECM capabilities with many innovative features not available in other ECM systems. As a result, we have found that many companies that use SharePoint wish to consolidate their IT infrastructure, by migrating content from older ECM systems into SharePoint.
While we think this is a great idea, such a migration requires a good deal of planning and design as well as specialized tools to automate the migration.
This slide deck provide detailed best practice guidance on how to plan for a migration of content from nearly any ECM system into MS SharePoint 2010 or 2013.
