I have posted an update to the blog recently that discusses a problem I ran into with using the IIUI DDM Migrator tool to extract data from a DDM File Room/Cabinet. Discusses the problem and the final resolution.
Applies to anyone migrating to DOCOVA, Quickr, FileNet, regardless, if they are using the IIUI Migrator tool.
