Make exact copy of a zoho installation

Make exact copy of a zoho installation

Here is the scenario:

I have one Zoho installation which I want to duplicate, including attached files, messages, basically - all of it.

At the moment, all accounts in their respective 'countries' running in one CRM. I spent some considerable time to 'fine-tune' the current installation. Also, almost every account has files attached to it.

It would take a long time to export, fine-tune again and so on. The fastest way is to duplicate to a new zoho CRM with a new login, company, etc. I would then simply delete the files irrelevant. Therefore, how do I duplicate or make exact copy of  ZOHO installation.

How do I do that?

Thank you.
