Can you clarify the role of your existing server, please?

Is it your only domain controller, or was it your first created domain controller?

Is Exchange installed on this computer or on another computer?

In that case,

1.  Configure the new server
2.  DCPROMO it as a new domain controller
3.  Transfer all FSMO roles to the new DC
4.  Make sure new DC is a global catalog
5.  Configure time sync on the new DC (NET TIME /SETSNTP ...)
6.  Keep the old server in the domain for a few days but powered off
7.  If everything is working, turn the old DC on, then...
8.  DCPROMO demote it
9.  Change computer so it is not a domain member
10. Delete computer from Active Directory Users & Computers
11. Review AD Sites etc. to check its gone properly

Also, I recommend that you get a second DC permanently.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

You can't do what you suggest unless you do a disaster recovery from a complete backup, and doing this to dissimilar hardware is a particularly difficult and fraught task.

Use a different server name, please, or you are only making life really, really hard for yourself.  It is possible to rename the server later, but again I would not recommend this approach.  You can read how here:

As you can see, it basically means setting up your new DC, renaming your old DC, transferring roles back to the old DC, renaming the new DC, and then transferring roles back to the new DC.

You have to use the same domain name as you are transferring the role of domain controller.
