Cert after upgrade

[carnold]

When following the instructions from the release notes after a upgrade and running these commands:
After you upgrade, the following commands run as the zimbra user will
regenerate the self-signed SSL certificates:
• sudo zmcertmgr createca -new
• sudo zmcertmgr deployca
• sudo zmcertmgr deploycrt self -new

When running the last/third command, i get an error:
Can't deploy cert for -new. Unknown service.
A quick google search returns nothing of value. Has this command changed in zimbra 6?
