Migrating eDir 8.8SP5 from NW to OES 11


This is more of a sanity check and solicitation of the prior experiences
with the similar migration scenarios.

I am planning a migration path from NW 6.5SP8 to OES11 and from the
training manuals and various online posts it looks like the following
approach of gradually phasing out NW servers should work:

1. add r/w replica on a new OES 11 server (and remove a r/w replica on
one old NW server, at this point we will have eDir 8.8SP5 on NW and eDir
8.8SP6 on OES 11 in the replication ring)
2. add a r/w replica on another OES 11 server (...and remove another
old r/w replica on a NW server)
3. add another r/w replica on a new OES 11 server and promote it to the
master replica
4. make sure there are no other NW servers left running (all file,
print, CA, SLP DA, timesync services are running on OES 11 at this
point)
5. remove the last r/w replica on the old NW server (... and remove the
last NW server from the tree)

Does this sound right? I don't see this specific scenario described in
the Upgrade, Migration or Best Practices guides.

BONUS question: what are the advantages of using the migedir utility
instead of just adding a replica on the OES 11 server (when the eDir
versions are close enough on NW and OES)?

Thank you!
Alexandr

Seems like a reasonable plan.

Keeping the server name the same.

You may want to review the documentation on replica types:

edir88/edir88/data/fbaecheh.html

Replica operations are done with iManager. No, you can't (normally) go
directly from a Sub Reference to Master. You'll need to add a Read/Write
replica of each partition to your SLES11 server, first, then you can
promote the Read/Write to Master if you want to.

Master vs. Read/Write is really a non-issue for almost all cases.
