Top Legacy System Modernization Firms

Many core systems still run on COBOL, Visual Basic, old .NET or Java monoliths that few engineers can maintain and that cannot connect to modern tools. Legacy system modernization companies replace or rework them without stopping the business: they assess the codebase, choose between rehosting, refactoring, rearchitecting and rebuilding, then migrate data and users in stages. Companies hire them when vendors end support, when the last developer who knows the system is retiring, when security audits flag unsupported software, or when a new product needs APIs the old system cannot offer.

Compare the firms here on modernizations of your specific technology and on how they keep the old and new systems running side by side during the switch.
