You can try to follow the discussion here:
https://bugzilla.redhat.com/show_bug.cgi?id=1240466

Basically you have to:
- take a backup of the engine with engine-backup
- deploy from scratch on an host pointing to the new storage domain
- - if you are going to use the engine appliance, here you have to
avoid automatically executing engine setup since:
- - - you have to manually copy the backup to the new VM
- - - you have tu run engine-backup to restore it,
- - - only after that you can execute engine-setup
- at the end you can continue with hosted-engine setup ***
- then you have to run hosted-engine --deploy again on each host to
point to the new storage domain

*** the flow is currently broken here: hosted-engine-setup will fail since:
- the old hosted-engine storage domain is already in the engine (since
you restored the DB) but you are deploying on a different one
- the engine VM is already in the DB but you are deploying with a new VM
- all the hosted-engine host are already in the engine DB

So you'll probably need to manually edit the engine-DB just after DB
recovery in order to:
- remove the hosted-engine storage domain from the engine DB
- remove the hosted-engine VM from the engine DB
- remove all the hosted-engine host from the engine DB since you are
going to redeploy them

We are looking for adding this capability to engine-backup
