Hello,
We have a custom Klaviyo integration for our ecommerce infrastructure, which has been using the v1/v2 APIs for a couple of years.
I have fully understood and tested the differences between event structure in the v1/v2 APIs and the new APIs and how to migrate event generating code from the old format to the new format.
However, what I can’t quite establish is, what happens to all the existing events data (and profiles) - do we need to re-upload all historical data in the new format?
I.e. Are historical events already uploaded via v1/v2 100% compatible with equivalent events uploaded with the new APIs?
Are we required to delete all existing metrics and re-upload using the new APIs?
Thanks in advance!
Mat.
