## Jerzy Zawadzki CTO, Polcode

**Webinar**

# Rebuild or Refactor?

**Moving forward from black-box legacy systems.   
CTO perspective**

Duration 50 minutes

### What will you learn?

In this webinar, our CTO will help you understand **how to deal with legacy IT systems**. Such systems often resemble a black box that everyone is afraid to touch. Here's the detailed agenda:

- **Maintain your sanity, not legacy systems**  
  Instead of feeling bad about not delivering on time, learn how to take a proactive approach towards diagnosing legacy systems, the issues, and how to strategize ahead.
- **Learn all the warning signs of old code killing business**  
  Are you building up technical debt? Symptoms like bugs, slow feature releases, incompatibility and missed opportunities are all signs that you need to perform an upgrade.

- **Know how to convince others of legacy upgrades**  
  Jerzy will walk you through how to measure the efficiency gain from refactoring older systems, allowing you to convince others to upgrade or migrate from legacy systems.
- **See why you should refactor over a complete rewrite**  
  Your legacy code is the treasure chest of knowledge and ideas, so throwing it away completely is almost never the right idea. Refactoring lets you incrementally get out of legacy hell.
- **Plan, make progress and track results**  
  Learn the tried and tested steps of the good refactoring process and make sure you have good benchmarks to measure your progress against.
