VisualAge Generator to Enterprise Generation Language Migration Guide


What is new in EGL that requires migration?

WebSphere Studio and EGL represent major changes and enhancements from VisualAge Generator, including the following:

The differences between the VAGen language and EGL are extensive. In the past when you upgraded from one version of Cross System Product or VisualAge Generator to a new version, there were only minor changes to the language. The previous migration tools were able to migrate each part independently of any other parts. However, due to the differences between the two languages, the VisualAge Generator to EGL migration tool must migrate each part in the context of other referenced or associated parts to determine the following:

Cross-part migration is the term used to describe this situation in which the migration of one part depends on other parts. Cross-part migration is required to produce the best possible conversion from the VAGen language to EGL. This in turn means that you need to carefully consider which groups of parts you migrate together.

Given the differences between VisualAge Generator and WebSphere Studio and the need for cross-part migration, this migration is a major undertaking and needs to be carefully planned.
