Can not upgrade container based on RHEL 3 standard OS template to RHEL 4 EZ OS template using the utility 'vzveconvert' if Plesk is installed in a container.


Red Hat does not recommend automated upgrading of RHEL 3 server to RHEL 4, as it provides a lower assurance of successful migration than administrator­-guided migrations. Instead, it is recommended to perform a fresh install of Red Hat Enterprise Linux 4 server, and then restore all configuration data, user data, and software applications.

More details about recommended ways to upgrade RHEL 3 server to RHEL 4 may be found on Red Hat website and in this document in particular -
