I’m setting up Azure Site Recovery and I’ve been told we can migrate machines and retain the IP addresses in Azure, I thought the azure address space needed to be different than on-premise, is it possible to retain all the IPs when migrating workloads to Azure? We will be doing an application at a time over a period of three months. Any thoughts?
Site Recovery simply by replicating an Azure VM to a different Azure region (Availability Set).Yes,it is possible to retain the IP address without impacting production workloads or end users.
In order to do that the Source (High availability Site) and Target (Disaster Recovery Site) should have IP address with same subnet.
Use Traffic Manager (Priority mode), it moves traffic to the next closest Disaster Recovery Site in Azure region if any one endpoint in unavailable state.If you want to define a preferred failover sequence, use nested Traffic Manager profiles too.
