Looks like Deb in Texas  did the following steps (cmiiw): 

1. Convert data from old QBO account to a QB Desktop file. One can utilize the conversion tool for free or purchase a 3rd party service.

2. Install the trial license for QB Desktop to open the file and prepare the new QBO account provided by TechSoup

3. Convert data from QB Desktop to the new QB Online account. Some data will be missed on the new account due to limitations in the conversion process (e.g estimate, attachments, custom fields)
