Modernizing Software

Modernizing Software

Software is constantly ageing. It ages not only because the technology is constantly evolving, but also because the business environment and therefore the demands on the software usually change faster than the software can be further developed. On the other hand, it must be recognized that software has made the success of the company possible in the first place.

This training shows tried and tested procedures for modernizing existing legacy software. This includes finding out what is particularly important and deciding objectively whether the effort for a measure is worthwhile at all. You will learn about tried and tested approaches to revising existing software as well as approaches to supplementing it with new software, possibly even replacing it completely in the long term.

Learning Objectives

Target Audience

Developers and maintainers of existing systems who spend too much time maintaining legacy software and want to implement changes and enhancements more quickly in the future.

Participants should have at least 1-2 years of experience in programming with PHP or a similar programming language. They should have experience with procedural and object-oriented programming and be proficient in using an IDE and common development tools such as Git version control.
