How to: copy a folder to another account/reporting database?

How to: copy a folder to another account/reporting database?

Hi there. Unfortunately for me, I am new with Zoho reports.
My question is: how can I copy a folder containing several reports, and a dashboard from another folder, to another reporting database. Can I copy these to another account in a specific database?
I found an " Procedure to copy the database from one account to another account" but along the way i get a message that tells me that the database could not be found. 

Thanks in advance.
