Progress Software has released OpenEdge 12. While significantly improved database performance and container-based deployments are huge incentives for upgrading to OpenEdge 12, Progress Software has discontinued the classic AppServer and WebSpeed in OpenEdge 12.

From a product management point of view, we can certainly understand this decision, however for customers using the classic AppServer or WebSpeed this may require some changes and could cause challenges. While in general AppServer and ABL client code does not require wide-reaching changes to be ported from the classic AppServer to PASOE, some minor code changes may be required here and there. A potential risk may be that PASOE is only supported on 64-bit platforms, so that usage of Windows API’s from within the AppServer application may require changes.

WebSpeed applications – especially when based on customizations – may require more code changes. Classic WebSpeed applications are supported through a compatibility Web Handler which may need to be adjusted to specific requirements.

Administration of the AppServer will require changes. As PASOE is based on the Tomcat infrastructure, it uses a completely different set of configuration files and command line utilities for interacting with the AppServer. Certain monitoring functions are provided as REST API’s only.

The advantages of the Tomcat infrastructure are large, including the ability to plug in Spring Security natively, greatly enhancing the security and robustness of your application.

Consultingwerk has deep experience with using both the classic AppSever and WebSpeed as well as PASOE. We can support customers during the administration and development of OpenEdge AppServer applications.

Our offer for AppServer to PASOE migration

AppServer migration may be performed along with an OpenEdge version upgrade or not. PASOE is available from OpenEdge 11.5 on (WebSpeed features from OpenEdge 11.6 on). We strongly recommend every customer that prefers to stay on OpenEdge 11 to upgrade to OpenEdge 11.7.4 ASAP.

Our offer is to provide a 3 days assessment first. During this assessment we will start with the review of the AppServer application and perform a high-level estimate of the whole migration process. During those 3 days we may already perform many of the tasks described inphases 1 – 5. After three days we will provide an estimate of the remaining migration efforts. At this time the customer can decide if they would like to continue or not with the migration with us or to continue on their own without any further obligation. However, we would be happy to support the customer during the complete migration to PASOE.
