When upgrading from ColdFusion MX†6.0 to 6.1 or 6.1 to 6.1 Updater†be aware that the cacert file will be overwritten.† This may be important to you if you rely on the CF internet protocol tags to connect to SSL enabled websites, including the CFHTTP and CFLDAP tags.

The default set of certificates stored in cacerts was increased between 6.0 and 6.1, but one person has confirmed that at least one default certificate was lost during that change.† If you performed custom imports of certificates into the cacerts file with the keytool utility, then both the upgrade and the update will overwrite the cacerts file and your custom certificate imports will be lost. You'll have to run the keytool utility again†to re-import those custom certificates.†
