Hey @neiltimmerman 
Welcome to the Postman Community! 
I fear that there is a bunch of context missing from this that will make it difficult to know exactly what happened for you.
If you were upgrading a previous Team that you had been using, I’m unsure of the need to move data to different Workspaces?
With exporting any data from Postman, if it’s not been saved or you have unshared variables, those will not be part of any exported file.
