Hi Expert,
I have the following scenario and need to some validation(s)
1. In a scenario where a customer has a main datacenter e.g. Main Datacenter A and with over 10 branch offices (sites) connected to the same WAN as the main center.
However, overtime the main datacenter will be decommissioned after all servers have been migrated to Azure using ASR. Will the ExpressRoute connectivity still be valid/established and will users in other branch offices still able to connect to Azure when Main Datacenter A is decommissioned after the servers migration is completed.
2. When it comes to site-to-site VPN co-existence with ExpressRoute can we have Multi-site site-to-site VPN set up also?
