50 years of paper digitized. Casino operations modernized. PDF portals made real-time.

Legacy systems we have replaced

ICC/cdpACCESS had 50+ years of paper-based construction procurement. We built a digital platform that moved an entire industry from paper to digital. Thousands of contractors use it daily. Wind Creek Hospitality ran fragmented legacy systems across multiple casino properties. We replaced them incrementally -- player loyalty, hotel booking, vendor management -- with 1,800% performance improvement and zero business disruption. Harbor Capital Advisors had a PDF-heavy legacy site where investors had to call someone to get fund data. We replaced it with real-time interactive data and mobile-first design. No big bang. No go-dark period. Piece by piece, the legacy systems disappeared.

What our clients are saying

“They’re the smartest group of people I’ve worked with; they can figure anything out. Caxy has respect for design. Other web firms often push back against designers if the designs don’t fit how they do things. By contrast, the Caxy team bends over backward to respect the original design concepts."

“They often go above and beyond to fully dig into a problem, identify solutions, and achieve our end goals. {...} We now can scale up our site and support future growth, thanks to Caxy Interactive’s efforts.”

Peter Anderson

‍CTO, Wind Creek Hospitality

“We feel like we’ve got a site that’s worth more than we paid for. The change that we were proposing from a redesign standpoint wasn’t going to be easy. So, he offered multiple times to come out and meet with many of those senior executives that have been with the company for 20 years.”

How modernization works

Phase 1 in 2-4 months. Full modernization in 6-18 months.

Step 1: Free 30-minute modernization call. Walk us through your systems. We will tell you which approach fits and give you a rough timeline.

Step 2: Technical assessment (2-4 weeks). We audit the legacy system, map dependencies, assess data migration complexity. You get a phased modernization plan with realistic timelines and costs.

Step 3: Phase 1 build (2-4 months). Highest-impact module modernized. Users see results. Business continues operating.

Step 4: Subsequent phases. Incremental migration until the legacy system is fully replaced. No big bang, no downtime.

Process Wins

ICC/cdpACCESS: 50+ years of paper moved to digital, thousands of daily users. Wind Creek: 1,800% performance improvement, 40% traffic growth, zero downtime. Harbor Capital: PDF-heavy legacy site to real-time interactive investor portal. All done incrementally.

Common questions

Questions about software modernization

01.

How long does modernization take?

Phase 1 in 2-4 months. Full modernization 6-18 months depending on system complexity. Every phase delivers standalone value.

02.

Will there be downtime?

No. Strangler fig pattern, parallel environments, incremental migration. Your business keeps running while we replace what is underneath.

03.

How much does modernization cost?

$200/hour blended rate. A Phase 1 modernization typically runs $100K-$200K. Full system modernization $300K-$800K depending on complexity.

04.

What approach do you use?

Depends on your system. Strangler fig for mission-critical systems. API wrapper for systems with good data but bad UX. Full re-architecture when the system is end-of-life.

05.

Do we need to rewrite everything?

Almost never. We modernize incrementally -- replace the worst parts first, keep what still works. Total rewrite is a last resort, not a starting point.
