(4.x to 5.2) Upgrading Replicated Servers
Chapter 2 Upgrading From Previous Versions 57
Refer to the Sun ONE Directory Server Administration Guide for instructions on
configuring replication for 5.2 servers.
(Optional) Reusing the Existing Port Number
After migrating data from the old server to the new, you may choose to retire the
old server and have the new server listen on the same port as the old. Using the
same port may allow client applications to continue operating without changing
their configurations.
Refer to the Sun ONE Directory Server Administration Guide for instructions on
changing the serverport. Be sureto stop the old server before the newserver starts
to listen on the old port.
(4.x to 5.2) Upgrading Replicated Servers
When upgrading replicated 4.x servers, start by replicating to a new master, and
then proceed branch by branch through the replication topology. This approach
limits the volume of server synchronization traffic.
Preparing the New Master
During the upgrade, the 5.2 server is configured as a masterbut functions as a
legacy consumer in the 4.x topology. After the upgrade, the 4.x consumer
capability is disabled, and the new server functions as a master in the 5.2 topology.
This procedure calls for manual configurationof the new masterserver. You may
therefore installthe new master on a different host than the existing master.
1. Proceed according to the instructions in Chapter 1, “Installing Sun ONE
Directory Server,” to install the new server.
2. Manually reproduce the configuration of the 4.x master on the new server.
3. Make the new server a master (for the 5.2 topology).
Refer to the Sun ONE Directory Server Administration Guide for instructions.
NOTE Refer to the Sun ONE Directory Server Administration Guide for
detailed instructions concerning replication configuration and
initialization.
