Sage HRMS Disaster Recovery - anyone has experience setting up Sage HRMS DR server at a vendor DR Data Center in the cloud?

Hello, we are trying to setup Sage HRMS at a DR data center with a vendor and go through an exercise simulating a Disaster Recovery scenario. We are wondering: whether:

1. We have to start a fresh install on the DR server?

2. or it is possible to restore a virtual machine file on the target server which will save time doing the installation during a DR scenario. 

Thank you for your time.
