Migrate datacenter with hosts and VM managed from engine no1 to engine no2
Hello, we have the current setup. => 1 datacenter on site A with 1 cluster which is compose of 3 hosts and a self-hosted engine => 1 datacenter on site B (let's call this TATA) with 1 cluster compose of 3 hosts which is using glusterfs. This datacenter is managed by the self-hosted engine on site A We want to create on site B another datacenter with 1 cluster and another self-hosted engine then disengage datacenter TATA from self-hosted engine on site A. after that, we want to import all the ressource on the self-hosted engine on site B Is it possible to do this without loosing VM on glusterfs ? Off course VM will be shutdown during the operation. I mean, when a host is added on a new datacenter, ovirt will install package if necessary. Is there any way that ovirt manager erase actual configuration ? Is it safe to do this operation ?

Hi, of course you can manually simply shutdown the VMs on the storage domain you want to migrate, detach it from the first engine and import it back in the second one. I'd also suggest to take a look to manageIQ which is the best response to manage complex environments composed by multiple engine from a single panel.

Hello Simone, at first, let me thank you for your answer. Ok for the storage domain. I have already done this before. The storage domain is a glusterfs domain. The glusterfs volume is composed of 3 hosts which are managed from the 1st engine. I wanted the detach the hosts, vm, storage domain from that engine and import everything on a new engine without loosing gluster volume info These are the steps I would like to do - stop all the VM - put into maintenance the storage domain - detach the storage domain from the datacenter - put all the host into maintenance - remove every host from the datacenter On the new engine: - create a new datacenter, cluster - add the host from the old datacenter (which does have glusterfs's conf) to the cluster - import the storage domain - import the VM from that storage domain Well I think I have to give a try on a test platform. Any advice about those steps ?
