Replacing a DS server

We are replacing one of our two 389 servers. I want to re-use the IP address of the old
server on the new one. What's the correct order of events for replication, shutdown
and replacement?

Thanks, Mike

Hi
Its difficult to say wiithout knowing how you have configured your two
servers...

In setups that I have had previosly I just rebuild the server (OS) and
install 389.
before I continue I remove the "old" server from the config database as
that was multimastered as well.
I then continue the 389 registration by running setup-ds.pl
I have lost my exact steps that I have followed but basically if you have a
multimaster environment the new server will just be viewed as a very out of
date master and for a while will be busy. You can populate it from the gui
which will repopulate the database.

@Gerhardus - Thanks for your help. I inherited the setup. 2 servers with multi-master
replication on RH 5.6 / 5.7. The new replacement server will be CentOS 6.2. Version info
follows.

The "old" RH servers:
[root@x-389-01 src]# ns-slapd -v
389 Project
389-Directory/1.2.2 B2009.237.2042

[root@x-389-02 ~]# ns-slapd -v
389 Project
389-Directory/1.2.2 B2009.237.2042

The CentOS server:
[root@x-389-01_v ~]# ns-slapd -v
389 Project
389-Directory/1.2.10.3 B2012.065.2318

Not sure I was much help. I am sure Rich will jump into the conversation. I
am proper back at work next week and can then dig around and give you a
more complete answer with regards to exact steps if you can wait that long.

@Rich, we are not re-using the hostname, just the IP address. --Mike

That's going to be a problem for replication, chaining, tls/ssl, 
kerberos, and anything else like that which uses the fqdn.

Thx for the heads-up. Would I be better off just adding the new server with a new IP
address as a multi-master, then removing the old one? Not re-using either the hostname or
IP?
