Modernization timeline estimator

A directional timeline range, not a quote. Enter your approximate lines of code and see what one documented real-world conversion suggests for scale.

This gives a directional range, not a quote. It is anchored to exactly one documented case (Blu Age converting 12 million lines of COBOL to Java for an insurance client in roughly 6 months) and scaled from there. Real timelines depend heavily on how tightly the code is coupled to CICS, IMS, or other systems that don't convert cleanly.

1 to 2 months

For a full automated-conversion rewrite of roughly 500,000 lines. This scales linearly off the one case we have data for, which is a real limitation: treat it as an order-of-magnitude check, not a plan.

For an actual estimate, talk to a vendor who does this for the language you're working with. Find one →
