Is there anything to consider before deploying an extra Exchange server?

Hello

CAS or mailbox role install?

Hi Thomas,

Thank you for your question.

If you want to add new CAS server to existed Exchange organization, we could consider the hardware of new CAS server, because when we install it, we will add it to CAS high availability.

If you want to add new Mailbox server to existed Exchange organization, we could consider the hardware and size of hard disk. Because when we install it, we will add it to DAG and it will be stored mailbox database.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim

Both acutally, I plan to replace the existing Exchange Server. Do I just install Exchange CU9 and then move the mailboxes to the new Exchange Server and then just decommission the old one?

My consideration are regarding installation and issues that could araise when installing a new Exchange Server in an existing Exchange organization.

Hi Thomas,

You could do it without any problems.

Do I install the Client access and mailbox roles during the initiale installation?

Hi Thomas,

If you just want to decommission the Exchange mailbox server, you could just install new Exchange mailbox server. If you want to decommission the Exchange mailbox and Exchange CAS server, you could install new Exchange CAS and mailbox server.

If there are any questions regarding this issue, please be free to let me know.
