We have a cloud server on Amazon EC2. Our old admin setup the DNS and Mail Server on one server that is working fine but I just realized now that the instance is on Instance store not an EBS backed. So the hardware could be failed any time and we will loose all our emails etc.
So I want to migrate that instance from Instance Store to EBS Backed instance, also I want to split the DNS from Mail(Zimbra Server) before the migration so our other sites should not effect with this migration.
I need some solution, how to migrate from Instance store to EBS instance with less down time.
