question about service communication certificat renewal(ADFS 2)

Hi,

Our service communication certificat will expire at the end of the month.

So we will import import a new certificat on the adfs management consol (ADFS 2.0)

My question is, the importation of the new communication certificat on the ADFS console, the token-signing and encryption certificat have to be renewed too?

For information  AutoCertificateRollover is set to true actualy.
