A page that contains blog posts cannot be migrated as BigCommerce API’s currently does not support any ‘Page Type’ with the attribute value ‘blog’. At present, blog-type pages can only be created in the Store Control Panel. This holds true, even with the new Page Widgets API

Additional note (Feb-2025): BigCommerce recently made a change so that a web page with the type of "blog index page" cannot be changed to a different web page type. This operation was not supported in the BigCommerce Control Panel and consequently, is now also prevented it via API.
‘The url is duplicate’ API notification (Pages, Categories and Products)
For Pages and Categories:
If you see this API error when migrating Pages, then it is likely because you have Category urls at the destination store with the same url value. And vice versa, check if when migrating Categories, if there are conflicting Page urls on the destination store. As long as you ensure there is no url conflict between Category and Page urls by using unique url values, the migration will work without issue.
For Products:
If you see this API error when migrating Products and if you dont see any Product with matching url value in the destination store, then BigCommerce support may need to run an orphan url cleanup tool, removing any unseen/remnant url links from your store data tables, to fix this issue. After the cleanup tool is used by BigCommerce support, the migration will work without any conflict on retry, after clearing the remnant url links.
