Coding agents add Db2 migration support to Cockroach Labs' MOLT in under two days

cockroachlabs.com 19 min read Editor score 8/10

A planning agent decomposed Db2 support into 15 dependent issues; the work took under two days and cost $4,172, versus nine months and about $160,000 for Oracle support. The case offers concrete evidence about agent-assisted engineering on a complex migration.

What: MOLT gained migration support for IBM Db2 sources, adding schema conversion, Fetch, Verify, CI, and test fixtures.
How: A planning agent split work into dependent sub-issues; agents opened fixes and pull requests, with reviewers sending work back 55 times.
Why it matters: The account reports under two days and no human-written code, illustrating agent-driven implementation with a review-and-test gate for production migration tooling.

MOLT fetches rows from Db2 into CockroachDB, then verifies the loaded data. Sketched from the article's own text.
