Handling IP Addresses During Test Failovers with Azure Site Recovery

For a site-to-Azure failover, provide a different Azure virtual network as the target that has the same virtual subnets and IP address ranges defined as production.

For site-to-site, you can either use network virtualization and use a different virtual network that uses the same IP address range as defined on the production network or you can use a different VLAN ID that doesn't have connectivity to the production network and that has the same IP address ranges as production.
