Re: [ovirt-users] Ovirt 4.1 testing backup and restore Self-hosted Engine

Hi again, I found this article https://keithtenzer.com/2017/0 5/02/rhev-4-1-lab-installation-and-configuration-guide/ I used the last section to delete the old hosted-engine storage, and it worked, the minute I deleted the old hosted-storage the system imported the new one and then imported the new VM-Manager into the Web admin portal.
