When using azure site recovery for DR site.
What happens to the IP, certificates, DNS at the replicated IaaS are the DR site when there is failover? Does Azure site recovery have a seamless process for DR failover?
If the subnets change between primary site and DR site than the IP will change? Therefore you will need to the change the DNS once failover occurs? The certificate on a web server have the primary site's IP therefore the web certificate needs to be changed?
