I am planning to migrate an /22 Subnet into a other datacenter. Currently i have announced every /24er seperatly.
My plan is, that i create a /22 subnet with the AS from the new datacenter on ripe. After i have migrated a /24 block i unannounce that /24 announcement and migrate the next ip block.
Does i understand it correctly, that when i stop the announcement of the /24 subnet, it will fall back to the less specific announcement and the IPs will be routed into the new datacenter?
