Prepare a catalog export you can actually reconcile.

Give every variant a stable identity

Use one row per sellable variant. Keep the source product ID and variant ID alongside the SKU, product name, option, price and inventory. Names can change; a stable identifier lets you trace a mistake back to its source.

Do not use a spreadsheet row number as the identifier. Sorting the sheet changes its position. Preserve prices as explicit amounts in a known currency, and distinguish blank inventory from a real zero.

Try three deliberately different products

Choose a single-variant item, a multi-variant item and an unavailable item. Include one with quantity pricing and one with more than one document. Import that small group first and compare the customer-facing result with the original records.

For example, a product with 5 mg and 10 mg variants should produce two selectable options, each with its own price and stock. Two identical product cards with no option selector are a reason to stop and investigate.

• Count products and variants separately.
• Compare the most expensive and cheapest variants.
• Check a zero-stock item and a missing-image item.
• Keep the unedited export as the reference copy.

Reconcile changes made during the move

If the old store keeps selling, its stock and orders will change while you prepare. Record the time of your export and decide which data needs a fresh update before switching the domain. A correct import on Monday can be stale by Friday.
