(4.x to 5.2) Upgrading Replicated Servers
58 Sun ONE Directory Server Installation and Tuning Guide • June 2003
4. Make the new server as a legacy consumerof the 4.x master (for the 4.x
topology).
Again, refer to the Sun ONE Directory Server Administration Guide for
instructions.
5. Initialize replication from the 4.x master to the new server.
The process is described in Chapter 13, Managing Replication,” of theNetscape
Directory Server Administration Guide. Referto the section entitled, “Manual
Consumer Initialization.”
You may now upgrade the consumers.
Upgrading the Consumers
This procedure outlines the approach. Refer to subsequent procedures for details.
1. Upgrade all branches in the 4.x topology.
2. Add additional servers to the 5.2 topology as required.
3. Disable the legacy consumer agreement on the new master to sever the new
topology from the old.
Upon completion of this procedure, the update process is complete.
Upgrading a Branch
Think of the existing 4.x replication topology as a tree with the master as the root
element. Here, a branch denotes a setof replicated servers in thattree for which the
flow of replication originates at the root node supplier, continues out through
consumersinthemidstofthetree,andfinallyarrivesatleafnodeconsumer
servers.
Upgrading a branch consists of replacing all old servers in the branch with new
servers, working from the top down.
NOTE While you upgrade a server, replication flow stops to all
downstream servers inthe branch. Consider redirecting client
requests to another branch during the upgrade.
