Hi all, after upgrading from Zimbra 7.2.1 to 8.0.0 on Ubuntu 10.04 I noticed the following errors in /opt/zimbra/log/mysql_error.log

Code:

Running a mysql_upgrade apparently got rid of them
Code:
/opt/zimbra/mysql/bin/mysql_upgrade -S /opt/zimbra/db/mysql.sock  -u root --password=yourpassword
(You can get your zimbra mysql root password by running zmlocalconfig -s | grep mysql_root_password )

I also tried to upgrade a clean installation on a vm with the same results.
Apparently zimbra installation is not calling mysql_upgrade, which seems to be recommended when upgrading to a major Mysql engine version (5.1 to 5.5).
Is this the expected behavior? Are there any other steps that need to be addressed manually (not mentioned in the release notes)?

Thanks
