For over a decade companies worldwide have used SmartDB Workbench and SmartDB Intelligent Adapters for migrating their data to Oracle Applications. Having been around for 10 years, the SmartDB Workbench is very robust. The Intelligent Adapters that SmartDB provide support Oracle Apps 10.7, 11.0.x and 11i (including 11.5.10). Information on all these products can be found at http://www.smartdbcorp.com.
The pre-built Adapters that SmartDB provide reduce the time and cost of migrating data to Oracle or upgrading one version of Oracle to another or consolidating multiple Oracle Apps instances into one.
THese tools are really easy to use and very cost effective. Some users claim that no Oracle Apps shop should be without SmartDB.
