A 2016 system left running on an OS that reached end-of-support in 2020. This is the record of migrating 3,623 tickets and 4.0 GB of attachments to a modern environment with zero data loss. Of the eight problems we hit, only three came from the application itself.

What used to take about a month of desk-bound comparison tables: with an AI agent we built a ~66,000-line prototype in two working days and, after measuring 10,000 records to confirm every API dropped from 22s to under 3s, locked in the architecture.
