Using Data Replication to Upgrade to Oracle 11g with Minimal Downtime

In these tough economic times, organizations are trying to lower costs in all of their business operations.

This white paper discusses the different types of migrations, their benefits and challenges. It also explains some best practice methodologies for minimizing downtime of applications on your Oracle database environment during these migrations.
