On the roadmap the "Namespace Transition Support" is listed. I was
wondering what the status of this is and what strategies people are
using as a workaround. Specifically I am interested in how to deal which
changes in an organizational structure.

Currently I am doing the following:

1. read the organizational structure from a human resources
2. construct a corresponding structure of folders in Grouper
using the web services interface
3. add a standard group to each folders
4. read the user data from the HR database
5. add the users to the standard group in the appropriate

If, say, HR decides to move a group from one unit within a department to
another, that group should remain a member of the department, but should
no longer be a member of any unit-specific groups.

I would envisage doing something like:

1. create new group in the new unit
2. add members of old group to new group
3. determine memberships of old group
4. recreate memberships which need to be preserved
5. add any new memberships required
6. delete all old memberships
7. delete old group

Steps 4 and 5 would require some human interaction regarding what
exactly should be done.

My questions are:

1. Is this the approach that other people are taking?
2. Are there any alternatives?
3. Will "Namespace Transition Support" provide this
4. When might NTS be available?
