<div>You'll probably need to recreate (or reschedule) routers if you have any, but it seems like your VMs should continue working and have connectivity (within tenant private network)</div><div><br></div><div>Thanks,</div>

Every thing is working fine but I need to change network node due to some hardware issue. Already more than 10 vms are running. I am not getting any way ?
