Any help would be appreciated.

It was our mistake.

Before the upgrade, we did a backup, but all the soft-links from /opt/zimbra were copied as directories.
When we tried to do the upgrade with this backup copy, as no soft-link exists in /opt/zimbra, this error had appeared.
We will try to do a new backup maintaining the soft-links.

Thanks,
Ricard
