The TLS certificate on my hub transports is about to expire soon. I inadvertently ran the command below without the -whatif parameter and generated a new cert on one of my two hubs. I noticed that the issuer is different than the current one cert. I tried to remove it but I got an error 
 
remove-exchangecertificate -thumbprint CFE500CCA6CC282E4E881E1EECEB9CCC3DD36E0B 
 
Remove-ExchangeCertificate : The internal transport certificate cannot be removed because that would cause the Microsof 
t Exchange Transport service to stop. To replace the internal transport certificate, create a new certificate. The new 
certificate will automatically become the internal transport certificate. You can then remove the existing certificate.

+ remove-exchangecertificate &nbsp;&lt;&lt;&lt;&lt; -thumbprint CFE500CCA6CC282E4E881E1EECEB9CCC3DD36E0B 
 
 
Will this cause a problem or can I simply create a new cert with the proper issuer informnation and then delete this one? 
 
thank you

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
