Avoid expensive legacy rewrites by renovating existing systems and leveraging innovative uses of automated test tools.

Rewrites are costly, and generally don’t lead to the outcome promised. Don't tear down your house—remodel! With legacy remediation our testing experience helps safely factor your legacy codebase while avoiding a costly rewrite.

Test Double employs a variety of techniques using automated testing to remediate legacy systems. Refactor with confidence, knowing your code is maintainable for years to come.

Considering a rewrite? There’s a better way.

Refresh your system!

Upgrade to secure, stable, and supported versions of the frameworks and libraries your mission-critical applications rely on.

So you get more than just a predictable upgrade plan. We lead by example and mentor your team on staying updated in the future.
