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
