export all the VMs from the all-in-one host 3. import them in the hosted-engine one When everything is in the new one and you are sure that it's working you could clean the first host to get rid of all the all-in-one stuff and redeploy it as an hosted-engine additional host.
thank you for you replies and suggestions. For suggestions of didi on CNAME effectively I did not think about it, then I will apply. For the migration I try to explain me better. As in my previous mail, currently I have installed a server with ovirt engine 3.4.1 (all in one). The hostname is the same of the User Portal url and this is registered in dns server (oveng.local). Since I have an identical server to the 'all in one' server, I would like to migrare the entire structure to ovirt 3.5. For the new installation of ovirt-engine I thought to install it as a virtual machine on vmware vsphere. Obviously adding also storage. I explain better, I thought to create a new parallel infrastructure to the one that is currently installed, for migrate to a virtual macchine. I would like to use the current hostname for the user portal (oveng.local). Once the migration will be terminate I will re-install the old server (all in one) as a host of new structure. To do this I thought to: - change the hostname of the old server (aio) from oveng.local to ovengold.local. - add a CNAME to the dns (as suggested by didi) - install the new ovirt-engine on an our vmware vsphere structure with the CNAME modified - configure the networking - install the new server as a node and add it to the new new structure. - add storage - migrate the virtual macchines from old structure to the new structure. - do the test - if its work fine I shutdown the old server (aio) - re-install the old server (aio) as a node and add it to the new new structure. What do you think? Best regards
