Service

Switching from another sync solution? We handle the cutover.

Most centres looking at Defyn SAM are already running something — manual CSV uploads, a custom developer-built script, or a competing plugin that's stopped getting updates. The fear isn't trying something new; it's losing the data and momentum you already have. Our migration service lines up a parallel-run period so the cutover is gradual and reversible.

The pain

The migration risks that scare centres off switching.

  • Years of accumulated catalogue data — artist biographies, edition history, manually-edited product descriptions — gets lost or duplicated during an automated re-sync.
  • Order history breaks: the new system doesn't know about historical sales, so reports and accountant reconciliation reference orders that exist in WC but not in the new connector.
  • Downtime window is impossible to schedule: the shop has to stay live for buyers, but two sync systems can't be active simultaneously without writing duplicates.
What it does

Three-phase cutover with a parallel-run safety net.

We've migrated centres from CSV-export workflows, custom Python scripts, two different competing plugins, and one home-grown PHP integration. The process is the same every time:

  • Phase 1 — Audit: we inventory what's currently in your storefront (products, artists, categories, sync state) and identify which records the old system owns vs. which were manually created. Nothing is deleted yet.
  • Phase 2 — Parallel run: Defyn SAM installs alongside the old system in read-only mode. We sync to a staging environment, verify product display + GST + freight against your real SAM data. The live shop keeps running unchanged.
  • Phase 3 — Cutover: the old system is disabled. Defyn SAM is flipped to write mode. We do a 24-hour close-watch period where both systems' last-known states are diffed and any drift is reconciled by hand.
How it works

What the migration timeline looks like.

  1. 01

    Pre-call audit (week 0)

    We ask for a screenshare of your current sync setup and a read-only export of your WC / Shopify catalogue. We identify the boundaries — what's SAM-sourced, what's manual, what's hybrid.

  2. 02

    Install + dry-run (week 1)

    Defyn SAM installs alongside the old system in read-only mode. We sync the full SAM catalogue to a staging URL. You verify the staging output matches expectations before any production change.

  3. 03

    Reconciliation pass (week 1-2)

    Edge cases surface: products that exist in WC but not in current SAM, manually-edited descriptions you want preserved, custom categories. We document each and decide per case — keep, sync over, or merge.

  4. 04

    Cutover (week 2)

    Scheduled at a low-traffic window (typically Sunday night Sydney time). Old system disabled. Defyn SAM flipped to write mode. First production sync runs. Test orders placed to confirm the end-to-end flow.

  5. 05

    Close-watch period (week 2-3)

    24 hours of monitored operation: Defyn engineer on call, every sync run reviewed in real time, any anomaly investigated within minutes. Stable after 24h.

  6. 06

    Handover (week 3)

    Team walkthrough of the new dashboard. Old-system credentials revoked. Migration sign-off. The 30-day priority support window kicks in from this date.

Where it kicks in

Migrations we've already done.

Scenario: Centre running a custom Python script written by a former staff developer. Script worked but nobody knew how to update it.

Result: We mapped the script's data flow to Defyn SAM's syncers, confirmed feature parity, then ran 14 days of parallel sync. After cutover the script was retired. Catalogue history preserved 100%.

Scenario: Centre on a competing plugin whose vendor stopped responding to support tickets in late 2025.

Result: Old plugin disabled. Defyn SAM imported the existing WC product catalogue (matched by sam_id meta where present, by SKU otherwise). Manual products untouched. Zero downtime — shop stayed live throughout.

Scenario: Centre running CSV export-import every Friday. Manual workflow ate 4 hours/week from the coordinator.

Result: Defyn SAM replaced the CSV cycle. Coordinator now spends 0 hours/week on catalogue sync. The Friday morning ritual is gone.

Questions

Frequently asked.

What if we have manually-edited product descriptions we want to keep?

During the audit phase we flag every product where the SAM-source content differs from what's live on your storefront. You decide per product — keep your manual edits, take SAM as source of truth, or merge. We don't overwrite anything you haven't approved.

Will historical orders still be readable in the new system?

Yes — Defyn SAM doesn't touch WC's order tables. Existing orders stay exactly as they are. Defyn SAM only governs how new orders push to SAM going forward.

How long does a typical migration take?

Three weeks end-to-end is typical. Smaller centres with cleaner data can cut over inside two weeks; large catalogues with messy historical state can stretch to four. We don't accelerate at the expense of safety.

Can we keep the old system running during parallel testing?

Yes. Phase 2 is specifically designed for this — Defyn SAM is installed in read-only mode (writes to staging, not production) while your existing system continues to drive the live storefront. No conflicts, no downtime.

What does migration cost?

Tailored to complexity. The cleanest path is a discovery call where we look at your current setup; from there we can quote concretely.
