install the same SSL on Edge transport accidently

Hi All,

I am configuring an Edge Transport, when installing the SSL that was exported from EX2010 on the Edge transport as follows:

Import-ExchangeCertificate -FileData ([Byte[]]$(Get-Content -Path "c:\Ex2010.pfx" -Encoding byte -ReadCount 0)) -Password:(Get-Credential).password -PrivateKeyExportable $true| Enable-ExchangeCertificate -Services SMTP

Confirm
Overwrite the existing default SMTP certificate?

..........

I should have answered NO, but I answered Y. 

Is there any way to reverse or fix it? Thanks

Regards
