How to install the INTERMEDIATE and SSL certificate on Exchange 2013

Hi

I have exchange 2013 and my predecessors has installed a SAN certificate on this server SSL® + UCC
Now I wanted to add another domain and i requested the SSL provider to add a new domain to the SAN certificate and I have been told by the SSL providers that the new domain has been added to the SAN and new certificates were issued on the portal.
On the SSL company website portal- Under my account I can see each of the following text on a separated windows.
I can see CSR text ,  SSL text, INTERMEDIATE text

So first do I need to copy the INTERMEDIATE txt on a notepad and rename as .crt and import into Intermediate Certification Authorities in the certificate mmc console of the Exchange server.
Secondly I copy only the SSL text to notepad and rename as .crt and Log in to Exchange Admin Center and import.
Thirdly Do I need to leave the CSR as it is ?

Please suggest if I am wrong or if I missed any steps?
Also do I need to remove the previous SAN certificate on the Exchange 2013, before I install an updated one.

Any help much appreciated. Thanks in advance

Generate CSR using EAC, then used new CSR to generate new certificate, then download the certificate, open EAC again and complete the certificate pending request and import new certificate, Then assign the services to new certificate.

The CSR is already available on the SSL provider portal under my account . This CSR was generated by exchange 2013 and  supplied to the vendor when procuring the SSL® + UCC.

So I have the SSL in a text and  INTERMEDIATE in text on the vendor portal under my account.
See my original post, instructions required to install SSL and INTERMEDIATE certificate.
