There are good reasons to use 1.2.9...

Copy DB files (if servers are homogenenous)

Use ldbmcat to generate LDIF, load LDIF in server via ldif2ldbm otherwise.
(Note: this assumes that all entries were originally loaded via
ldapadd(1).  Ldif2ldbm should not be used to load 'new' entries).

Temporary set the rootdn/rootpw to be the updatedn/updatepw, add
the update dn entry to the master, replicate to slave, and then
change slave such that updatedn points to added entry.

Assuming that the difference is significant, it's not safe.

See above.

If properly configured, the slave should refer all writes and all
superior requests as indicated by the "referral" server.
