Update OracleVM (servers and manager) to a specific versions

Hi all,

Hope you all are great.

I've a specific need to update my OVM server pools  from 3.4.2 to version 3.4.5 (because of VM's running in PVM mode for now), but if I use the OVM Manager update feature, I'll end into version 3.4.6.3.

Is there a simple way to update (using OVM Manager) to a specific version?

I know that I can use a ISO file of a specific version (in this case 3.4.5) and mount it in a local HTTP server and then provide that to OVM Manager, yet this will not fix all security issued...

I also know that I can use Spacewalk as the yum provider, but even for this I had to use a 3.4.5 ISO file to feed the Spacewalk repository.
