I created a design using a free account and we realized that we needed an upgraded account. How do I transfer my design from my free account to the company paid one (that has a different log in)?
As you probably know, in order to take advantage of paid features, a form must be authored by a paid account. While there is no mechanism to change the owner of a form, what you can do is share the form with your paid account and then have the paid account duplicate it.
First, share the form with your paid account by following these instructions:
Then, log into your paid account. Select the shared form in the list and select the duplicate button on the toolbar (shown below). You now have a duplicate copy of the original form, with your paid account as author.
