Move critical code forward without freezing the business
We walk alongside engineering leads who inherit COBOL batches, monolithic Java estates, or vendor-locked ERP extensions—and need a migration path their board will fund and their operators will trust.
What we take on
Our work sits at the intersection of code archaeology and delivery planning: naming what must keep running, what can be strangled, and what evidence you need before cutover weekend.
Target-runtime selection
Honest trade-offs between rehost, rewrite-in-place, and phased extraction for your compliance regime.

Cutover rehearsal support
Playbooks, rollback criteria, and paired hours during dry runs—not a slide deck left at the door.
Migration executionA recent engagement in Gauteng
A municipal utilities back-office still posted ledger entries through a 1990s client-server suite. Silicon Relay spent six weeks mapping interfaces to a newer billing hub, then coached two in-house developers through a strangler release that kept nightly balancing intact.
They insisted we record every manual workaround before touching code. That felt slow on week one; by week four it saved us from migrating a report nobody had run since 2018.

Start with a bounded review
The Legacy readiness review is a fixed-scope engagement: one primary system, up to three integration points, and a written recommendation you can attach to a funding memo. Most reviews complete in ten working days.
