Upgrading Servers with
Replicated Databases

Introduction

After you have upgraded, you will no longer be able to scan any part of
the transaction log that existed before the upgrade, so you must follow the
following process if your server contains replicated primary databases
(this includes replicated RSSDs). This procedure will help to ensure that
all replicated data from a replicated database has made it safely to the
replicate database.

Warning!

It is not sufficient to simply get the replicated data into the

Replication inbound queue, you cannot rebuild the inbound queue after
the upgrade.

The procedures described here do not upgrade Replication Server itself.
For information on upgrading Replication Server, see your Replication
Server documentation.

The database upgrade procedure consists of:

Suspending transaction processing and replication activities.

Draining transaction logs for primary databases.

Draining the Replication Server System Database (RSSD) log.
