I have a client that sold his business - he is on QBO. The new owner wants me to convert this QBO file to 2018 Pro for desktop. I have learned how to convert the file in QBO and give him the file to use with his copy of QB. 

I have having a hard time figuring out where to import the file - I have Accountant 2019 but if I toggle to the 2018 Pro I believe that I can only send him the accountant's copy. I need to send him the entire file. 

I read Using an Accountant's edition allows you to install multiple versions of QuickBooks on your computer.  But when I try to download the 2018 Pro it is asking for license and product info. Do I have to buy other versions? Do I have to buy 2018 Pro to be able to convert the file, work on it and send it to the new guy as a backup

I am new at using the Accountant version.

Thanks!
