This worked.  The only snag I ran into was the pid file in the 
slapd-[host]/logs directory.  Permissions looked ok, but until I actually 
removed it did it fire up and run.

Replicaton and all seems to be working.

I still have my other replica to redo so I will have a chance to double verify 
this migration path.

Will post if anything bad happens.

Thanks Again,
