Hi Raghav; As per my experience [lesson learn]; I can second to Mr. Azhar that we had use parallel ISP connection with our services like email/VPNs with metric/cost set to higher for the newer IPs [say cos/metric=40, and the older IP address cost was 10] and after 12 hours we switch the metric to lower of the existing older IP addresses.
Hope this will help you out to seamless migration of network switching.
