Updating the virtual appliance

Hi,

during the past years we "updated" CipherMail installations by installing a new virtual machine and imported the backup of the running system.

But what about performing an in-place update?

Let's say we have version 4.5 running with the following packages installed:

djigzo-network-4.5.0-0.noarch
djigzo-web-4.5.0-0.noarch
djigzo-log-4.5.0-0.noarch
djigzo-web-network-4.5.0-0.noarch
djigzo-web-log-4.5.0-0.noarch
djigzo-gateway-console-4.5.0-0.noarch
djigzo-4.5.0-0.noarch

Installing the rpm packages for version 4.11 (rpm -U djigzo-4.11.0-0.noarch.rpm djigzo-web-4.11.0-0.noarch.rpm) only updates two packages in that list:

djigzo-network-4.5.0-0.noarch
djigzo-web-4.11.0-0.noarch <----- !!
djigzo-log-4.5.0-0.noarch
djigzo-web-network-4.5.0-0.noarch
djigzo-web-log-4.5.0-0.noarch
djigzo-gateway-console-4.5.0-0.noarch
djigzo-4.11.0-0.noarch <----- !!

Should I be concerned about the mix of version? May it cause any trouble?

Thanks for any suggestions or comments,

Stefan
