Hi everyone,

We are changing our CMS from Prestashop to Shopify

So far, I believe a sensible course of action would be:

  1. Migrate all historical sales data from PrestaShop to Shopify
  2. Connect Shopify to Klaviyo using the native integration
  3. In parallel with steps 1 and 2, clone our existing Klaviyo flows and adapt their triggers and conditions to the new Shopify metrics — keeping them in Draft status
  4. Verify that the historical data is fully available in Shopify and that the new integration is syncing correctly
  5. Activate the new flows and deactivate the old ones
  6. Disable the PrestaShop integration in Klaviyo

Does it make sense? Did I leave out any steps?

Many thanks in advance
