In order to upgrade to 7.1 we created a new site, but there doesn't seem to be anyway to move the blogs over.
I tried exporting and reimporting to/from a wordpress file but SS errors out on it's own import.
This is the error I receive
— com.squarespace.v6.business.content.exceptions.InvalidContentItemException: urlId cannot be null: XLF2CRTZWNRFE489K3GY
