5.3.6. Upgrading Servers in Replication
The process for upgrading servers in replication is the same as for a single server, but the order in
which the Directory Server instances is important to keep from interrupting replication. First upgrade all
supplier servers, then all hubs, and then all consumers.
Always stop directory writes to the master or hub server before beginning the upgrade process.
After upgrading all of the supplier servers, then upgrade all of the hubs and, last, all of the consumer
replicas.
Then, after the Directory Server instances is upgraded, test replication to make sure it is working
correctly.
A supplier, hub, or consumer can be migrated to a different or platform as described in Section 5.3.3,
“Migrating an 8.x Directory Server to 9.1 ”.
5.4. Upgrading Password Sync
The Password Sync service cannot be upgraded directly. However, the existing certificates, keys, and
configuration can be applied to the new service if the new service is installed before the old one is
removed. T hen, it is not necessary to reconfigure the service like new; it picks up the information it
needs from the registry.
1. Download the PassSync.msi file from the appropriate Directory Server channel in Red Hat
Network and save it to the Active Directory machine.
NOTE
There are two PassSync packages available, one for 32-bit Windows servers and one for
64-bit. Make sure to select the appropriate packages for your Windows platform.
2. Double-click on the PassSync.msi file to install it.
3. All of the previous information should be included, so click Finish to install the new Password
Sync.
The previous SSL certificates and configuration is also preserved, so it is not necessary to
reconfigure SSL.
4. Open the Add/Rem ove Programs window.
5. Select the older version of Password Sync and click the Rem ove button.
NOTE
Check the version numbers to make sure the right Password Sync service is removed.
6. Reboot the Windows machine to start Password Sync.
