How to switch Google Shopping feed apps without changing product IDs
Compare the previous feed with the proposed feed before you change data sources in Merchant Center.

1. Export both feeds for the same market
Use snapshots for the same country, language and catalog scope. Keep product IDs as text so leading zeros survive. If possible, include a stable SKU or GTIN in both exports.
2. Review changes in product identity
Google recommends keeping product IDs stable. In the worked example, MUG-BLUE becomes shopify_12345 while its SKU stays MUG-BLUE. Treat an ambiguous SKU or GTIN as a manual review item.
3. Check price, stock and variants
Review currency, availability and item group IDs for changes you did not plan. Confirm the proposed values against product pages and verify the approved products in Merchant Center after the switch.
