Transfer workspaces from current multi-user account to an already existing business account

edited 12/09/19 in Smartsheet Basics

Hi.  Our group within the company has been using smartsheet for a number of years.  Recently corporate has launched our corporate account and we need to cancel our existing account and migrate all the data into the new corporate account.  Is there an easy way to do this or do I need to export all the workspaces out and back in again?  I've seen the posts on transferring ownership but I just don't quite understand if that's what we need to do.
