       The identity transfer should work. There are things to pay attention to,
however. Start with ensuring NTP time is proper on both boxes. Ensure server
IP names are properly registered in the visible DNS servers.
       The transfer process first requests services to migrate. You need not
do any, but you can choose say files to keep it happy and save you extra work.
Once those finish the eDir transfer part begins. In the past this step has
always resulted in eDir being removed and hidden on the source server. No
longer; just reboot the source server and all is as before.
      After the eDir movement there starts changing IP number and host name.
Beware: remote connections will break. Best to do this at the destination
console, or login again and restart the GUI. Double check the number and
name parts by opening a text mode window and look very carefully indeed.
   echo $HOSTNAME
will show the old destination name until you login again, as that item is
held in the user's login environment. /etc/HOSTNAME and /etc/hosts should
have been updated though.
      The last step is to reboot the destination and up things come.
      What you will be going through is a combination of Novell's command
line utilities fronted by the GUI plus my redesigns of the process during
the beta phase. The material is drastically different than found in the
public beta (aka beta 4).
      Bottom line: the source remains intact, you can do the whole thing
over again. But if you do retry, then first clean out eDir objects with
the destination name and afterward rebuild the destination server (don't
just try to "fix" it).
