List,
I am in need to migrate a Virtual machine ( running in an old OpenStack environment with only one controller). This VM has its own disk file + a logical volume attached to it with application data on it. Only Cinder backend( No rbd/ceph backend configured ) for this environment.
Now I am migrating this Virtual machine to another OpenStack(ussuri with three controllers, three compute nodes and three storage nodes) environment with ceph/rbd backend.
I am able to export the VM with its disk file and import it to the other openstack environment and able to boot the machine.
But How to export the attached logical volume from the old VM and attach to the VM in the other environment ?
what is the methodology to follow to export this logical volume in the old openstack VM and import to the new VM running in the other openstack environment ?
kindly share your suggestions/expertise to perform this
Thanks in advance for your valuable guidance. Krish
