[ovirt-users] Upgrading

[Fernando Fuentes]

Is there a best practice when upgrading from ovirt 3.4 to 3.5?
I upgraded my development server which is a self hosted server and I 
just did a regular update without putting anything under maintenance... 
Though my vm's where turned off. It all went well and the migration from 
krb/ldap to AAA went smoothly and so far is running like a champ.

I am about to do the same to our production cluster and was wondering if 
I must put all Hosts under maintenance before I do the upgrade? Is it 
any different than a self hosted ovirt setup?

Thanks in advance for all/any tips from the mailing list!
