[Users] general questions ovirt-engine migration 3.0 /use of ovirt-node/monitoring ovirt node

[Sven Knohsalla]

Hi,


I have some general questions I couldn't find answers in the web about ovirt-engine migration:

Currently we're running an ovirt-engine 3.0/ ovirt-node 2.3.0 environment,

If we want to migrate to 3.1, do we also have to migrate to 3.2, or is a "simple" update possible, or is it worth to wait with migration until 3.2 has been released?
Hint:  A migration(import/export) with about 50 VMs is time-intensive, as we need to plan maintenance windows for every VM :/

We also want to test newer ovirt-nodes & default fedora, I didn't find any info about operability with ovirt-engine 3.0:
Can we mix 2.3.0 node with latest version under ovirt-engine 3.0 or is there any problem with vdsm or anything else?

Monitoring:
If we wish to install check_mk (monitoring) on ovirt-node, how can we make sure the installation will be persistent?
(Collectd can't be used in our environment)
The alternative would be , to use default fedora installations, customized as ovirt-node.
(But this should be our last choice)

Thanks in advance!

Best,
Sven.
