We are planning to migrate to Struts 2.3.24.1 from Struts 1.1. Here are our questions:
We have large and complex case management application that uses struts and struts menu version 1.1. The application has over 1,000 pages many of which contain many data elements. The effort required to upgrade and test a large application to Struts version 2 looks very large. The effort to upgrade and test the entire application in a single release looks undoable. Questions: 1) Are there any software tools that can be used to speed up the time to update JSPs, page validation, tag library calls, Action classes, etc to reduce development, improve code quality, and reduce testing time? 2) Can a single application use both Struts 1 and Struts 2 at the same time? a. Would it be feasible to use Struts 2 for any new pages and upgrade to Struts 2 for any pages being changed for other reasons? b. What are considerations for groups of pages would need to be converted together (for example shared conversation for page flows) 3) We do an application release every 6 weeks or so. We can't do this in one release unless we find or develop a tool to help us convert pages to Struts 2. We are considering upgrading 100 pages per release to Struts 2. Has anyone done something like this successfully? What are best practices and lessons learned? 4) Test effort. With all of the code changes required it seems that developers could miss things. Everything we have seen so far indicates that this will be a huge effort for both development and testing. We are trying to find ways to streamline/automate some of this effort. Any help would be appreciated. CONFIDENTIALITY NOTICE: This communication with its contents may contain confidential and/or legally privileged information.
