Exchange 2013 - Create Master Hierarchy Public folder mailbox

Hello Guys,
I Have exchange 2013 , i tried to create Public Folder but i have couple of issues:
1. When I'm creating a public folder mailbox it's created automatically as 'secondery hierarchy'.
2. I tried to remove the public folders secondery hierarchy that created but i'm getting this:
"No active public folder mailboxes were found"

How to change one of my secondery hierarchy to praimery ? or how to remove all of the secondery hierarchy and create a new praimery hierarchy public folder mailbox ?
I don't see any praimery hierarchy public folder mailbox :(

Once you create the Primary Public Folder Mailbox (Hierarchy) this cannot be changed. This is the only Public Folder mailbox which holds a Writable Public Folder Mailbox. Secondary hierarchy mailboxes only hold a read-only copy.

This is one thing you need to be cognizant about when creating the first public folder mailbox in Exchange 2013. I would also make sure that this mailbox is in a DAG as well so that it is highly available. If you lose this mailbox Exchange Public Folders will not be accessible.

So to answer your question you will need to re-create the hierarchy. Take a look at the link below which outlines all of the details regarding Exchange 2013 Public Folder Mailboxes.

Agreed with Will.
You have to remove then re-create the primary hierarchy. You can't change the type.

Please advise.

You will have one somewhere, but perhaps you can't see it.
This should show it:

When you recreate the structure make sure you give it a clear name and document it.
