We moved our voice environment to fully qualified domain names. Since then I have multiple expired certificates callmanager-trust certficates where the common name is the host name. However I have the new certificates where the common name is the fully qualified domain name that has a valid certificate. Can I just delete the expired callmanager-trust certificates that are expired and keep the valid certs with the full fqdn. It seems like they do the same thing but I'm not very familiar with certificates. Thanks in advance. For example:
