Strategies for software source migration

在商业和软件行业中，可靠的软件系统是公认的价值;但是在快速发展的软件开发世界中，经过验证的系统必须不断适应不断变化的外部条件。 加拿大软件业的竞争力和健康取决于此。当一个现有的系统适应一个新的环境时，一个新的编译器或编程语言，或不同的支持软件和操作系统就会出现。管理这种适应的一种方法是“源代码迁移”，这涉及到对源代码的重大更改，以便在新的环境中正确地维护它。在拟议的研究中，我们开发的软件设计恢复从源代码，和自动化的源代码转换策略，四个标题：多层软件架构，方言（编译器版本）迁移，面向对象的框架迁移，并使用动态和静态分析的快速迁移计划。

Proven software systems are established value in business and in the software industry; but in the fast-moving world of software development, proven systems must constantly adapt to changing external conditions.  The competitiveness and health of Canadian software industry depends on this. When an existing system is adapted to a new environment, a new compiler or programming language, or different support software and operating system appear around it.  One way to manage this adaptation is by "source migration", which involves substantial changes to the source code, in order to maintain it properly in the new environment. In the proposed research, we develop software design recovery from source, and automated source transformation strategies, under four headings: multi-layered software architecture, dialect (compiler version) migration, object-oriented framework migration, and rapid migration plans using dynamic and static analysis.
