Hello All........I have an existing environment running Exchange 2013 CU6 with two-2 CAS and two-2 MBX. I want to add new servers that is two-2 CAS and two-2 MBX based on Exchange 2013 CU10. I have following questions:
1. Where should I start from; build CAS Servers first or MBX Servers first?
2. While installing what permissions my account should have?
3. While installing, would I be asked to joing to existing exchange organization? If so, what options should I select so that it does not affect existing environment?
4. Would it in any way cause any distress to the existing environment?
5. Would adding CAS add additional connectors to the organization and would the new CAS servers be also handing traffic?
6. Would I need to generate new certificate request for new CAS Servers or I can just import old CAS Servers certificate?
7. Would I be needed to set the same internal and external URL as old CAS Servers?
8. Can I set the same internal and external URL to the new CAS Servers as old CAS Servers? Would it affect in negative way?
9. Can I delete the default databases that get created on new MBX?
