Appendix. Migration from SOA Suite 10g to 11g

Many organizations have adopted Oracle SOA Suite 10g in the recent past, using BPEL Process Manager, the Enterprise Service Bus, Human Workflow services, and/or Web Services Manager. Such organizations typically have made considerable investments in their environment, the SOA applications, and the skills required to develop the applications and administrate the infrastructure.

With SOA Suite 11g, these organizations may feel like they are up against the “dialectics of progress.” They were the first to adopt Oracle’s SOA offerings and as a result they now have to make additional investments to upgrade to this latest release, even though it may seem the upgrade does not have immediate benefits. However, much of the investment is not lost, but can simply be applied to SOA Suite 11g. And these early adopters are best equipped to appreciate many of the improvements available in Oracle SOA Suite 11g over the previous releases of the SOA Suite. Finally, Oracle has provided various tools that support the migration. As a result, it may not be as earth-shattering, risky, or costly as it appears from a distance. On the other hand, migration is not something that can be done overnight in a few hours.
