Use existing SSL certificate in Zimbra?

[nosebreaker]

I have an Apache cert (signed by godaddy) and I want to use it in Zimbra. All the instructions I see so far are telling me I should create the CSR in Zimbra and then have Godaddy/etc sign it. But I already have the private key and the signed cert, how can I tell Zimbra to use it?

I see in /opt/zimbra/ssl there appears to be a commercial certificate and key, but I also need to give it the godaddy CA and intermediate certificate. Any help on what files I would need to replace would be greatly appreciated.

I figured it out. For anyone else in the same boat, replace the following files in /opt/zimbra/ssl/zimbra/commercial/
commercial.crt
commercial.key
commercial_ca.crt (use intermediate cert, called gd_bundle.crt)

Then I ran:
su - zimbra

/opt/zimbra/bin/zmcertmgr deploycrt comm \
/opt/zimbra/ssl/zimbra/commercial/commercial.crt \
/opt/zimbra/ssl/zimbra/commercial/commercial_ca.crt

zmcontrol stop
zmcontrol start
