01
Two-stack parallel run
Before cutover we mirror live traffic against the new stack and diff the responses. Anything that doesn't match — a price, a tax line, a shipping option — gets fixed before we touch DNS.
Replatforming
Replatforming, without losing a revenue weekend.
Migrations are where most agencies hide their worst engineering. We don't. Every Plus migration we run starts with a written cutover plan, a rehearsed rollback, and a parallel-run window where both stacks accept traffic until we're certain the new one is honest. We've moved brands off Magento 2, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and legacy Shopify Lite — and we've never lost a revenue weekend doing it.
Outcomes
What you actually get.
- Zero-downtime cutover with a rehearsed rollback path
- 100% URL parity preserved (every legacy URL maps or redirects)
- SEO equity preserved through the cutover and beyond
- Customer data migrated cleanly with passwords reset gracefully
- Order history visible in new admin from day one

Methodology
How we approach the work.
Not principles for principles' sake — these are the practices that decide whether we ship something good or something we'd be embarrassed by.
02
Rehearsed rollback
We run the rollback in staging before we run the cutover in prod. If something breaks at 11pm Friday, the team has muscle memory for putting the old stack back, not a Notion doc nobody's read.
03
SEO preservation
Every legacy URL is mapped or 301'd. Sitemaps regenerate. Structured data carries. We monitor Search Console for the 60 days following cutover and catch ranking drops while they're still recoverable.
04
Data migrated, then verified
Customers, orders, products, content — all migrated through scripts we run dry first, then for real, then verified with a row-count audit and a financial reconciliation against the source system.
05
Cutover during low-traffic windows
We never cut over before a sale or during peak season. The window is agreed up front, communicated to your CX team, and instrumented with a real-time health dashboard the whole team watches.
