CRM 2013: Adding a new server to existing IFD

Hi

I have IFD implemented on my servers for CRM 2011. Now, I want to add a new CRM 2013 server and configure IFD for it.

2011 already uses a wild-card certificate.

I have imported certificate on CRM 2013 server and configured CLaims based authentication.

My question is:

1. Do I need to create new DNS entries for my CRM 2013 IFD ?

2. Do I need to  add and configure claimers provider trusts and relaying party trusts in ADFS again?

3. Other than above 2, is there any other task I need to do on DNS or ADFS server.

Thanks
