Hi, I was able to remove the hostedEngine VM, but I didn't succeed to remove the old hostedEngine Storage domain. I tried several time to remove it, but I couldn't, the VM engine goes in pause mode. All I could do is to detach the hostedEngine from the datacenter. I then put all the other data domains in maintenance mode, the I reactivated my master data domain hoping that it will import the new hostedEngine domain, but without luck. It seems like there is something missing in this procedure.

Hi again, I found this article https://keithtenzer.com/2017/05/02/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.
