A couple of issues after Migrating to Exchange 2019
Hi tesla1886
I understand you have a working certificate on one Server (probably the public certificate) and want it to transfer to another Server.
On the working Server export the Certificate (from the Local Computer Certificate Store) to a PFX File with a Password including the private Key
Copy the PFX File to the new Server open Local Computer Certificate Store (certlm.msc) and import the PFX.
Make sure you have the Root Certificate and Intermediate Certificates from your certificate in the appropriate stores.
Then use Get-ExchangeCertificate and Enable-ExchangeCertificate to enable them in Exchange.
Regards
Andres

I didn't intend to transfer the certificate from the old server to the new one. I intended to rekey and replace it. I just don't know what the full process is and can't not find anything to tell me.

Hi tesla1886

Import Certificate into Certificate Storecertutil –repairstore my <serial number>
If you have a new private Key then you made a new CSR?
You should see a pending Request in "Certificate Enrollment Request" of your Cert Storehttps://blog.icewolf.ch/archive/2014/09/24/create-san-csr-with-certutil/
#Install the certificate with certutil
