Legacy Modernization and Software Maintenance
Assess legacy modernization, data migration, software maintenance, recovery, and ownership without disrupting essential operations.
Planning this work
Modernization is a controlled change to a living business system. The plan must preserve critical behavior and data while improving the parts that create security, reliability, delivery, support, or ownership risk.
This collection explains how to inventory an inherited application, establish operational evidence, choose incremental boundaries, rehearse migration, and define rollback. It helps buyers avoid a rewrite that discards undocumented business knowledge.
