When possible, a best practice is to generate test cases and a testing framework on the legacy application before migrating it. Then, equivalent test cases on the new application can be used to benchmark results across the two application versions.
“AI-powered testing frameworks further accelerate the process by auto-generating test cases, integrating security checks earlier in the software development lifecycle, and optimizing performance benchmarks for the new platform,” adds Shriki of Descope. “These advancements not only reduce technical debt but also allow teams to modernize applications faster without compromising quality, security, or developer effectiveness.”
Plan the data migration
Even after testing the application and its dependencies, a data migration may be necessary. This migration may be simple if the database technology and schema don’t require changes; for example, translating a small, on-premise SQL database to a cloud database service. However, if the schema changes significantly or data quality issues need fixes, the migration could be a project in itself.
