[Fedora-directory-users] Migrating Netscape DS to FDS

Hi, I have an old Netscape Directory Server version 4.1 (circa 2001) that I need to migrate to Fedora Directory Server, but I am confused as to the proper migration path. I've been reading the Red Hat DS install guides at http://www.redhat.com/docs/manuals/dir-server/ (as there doesn't appear to be as a comprehensive guide for Fedora DS. The Redhat DS 8.0 guide says that migrating Netscape DS 4.x is not supported (only version 6 and above), so I read the Red Hat DS 6.0 install guide and it says that Netscape DS 4.x is indeed supported. So am I right to presume that a step-upgrade will be required, from my current version 4.x to 6.x and then to the current version 8.0? Also, what version of the Fedora-DS is equivalent to Red Hat DS 6.0? Thanks -Dave p.s. If somebody can tell me how to search this list's archives that would be much appreciated!
