Collaboration with cross-functional teams—including application developers, security specialists, and project managers—is essential to ensure seamless integration and to address potential issues proactively. Staying updated on the latest integration tools and best practices also helps in overcoming these challenges efficiently.

Can AI replace mainframe?
