Want to end legacy codebase misery and learn how to reignite your old IT system? Join our on-demand webinar hosted by our CTO - Jerzy Zawadzki.

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 are 5 key takeaways:

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.
