I migrated a server from Exchange 2010 to Exchange 2019 this weekend. I currently have two issues I need assistance with.
Can anyone assist me with either or both of these issues?

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.

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
If you have a new Certificate with the current Private Key

Import Certificate into Certificate Store
certutil –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 Store

#Install the certificate with certutil
certreq -accept -machine C:\Install\test.cer
