-----END CERTIFICATE-----

Now let's check our certificates are verified via Zimbra certificate manager
/opt/zimbra/bin/zmcertmgr verifycrt comm privkey.pem cert.pem chain.pem 
If you see done message in your console, first make a backup of course...
cp -a /opt/zimbra/ssl/zimbra /opt/zimbra/ssl/zimbra.$(date "+%Y%m%d")
cp /opt/zimbra/ssl/letsencrypt/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.key
Soooo, we are ready to deploy new certificates, run deploycrt command via zmcertmgr.
/opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem chain.pem 
at last, here is a happy restart.
su zimbra
zmcontrol restart
