| ## Overview - Using the CDS Subtree Commands to Restructure CDS Directories Sometimes, because of corporate restructuring or for other reasons, you need to combine or rearrange various directories or subtree of directories in your CDS namespace. For example, suppose the engineering group in your organization, /.:/eng, is combined with the research and development group, /.:/rnd, and that the two groups begin to share a common set of applications and other network resources. You can reflect this organizational change in your namespace hierarchy by merging the contents of these directories. Similarly, if the engineering group becomes subordinate to the research and development group, you can reflect this change by creating an empty directory named /.:/rnd/eng and then merging the contents of the /.:/eng directory into /.:/rnd/eng, effectively appending /.:/eng below /.:/rnd. ##
