Update nameservers to new server?

Hello i have one problem i have 3 servers server1 with nameservers: - ns1.server1.net (127.0.0.1) - ns2.server1.net (127.0.0.1) server2 with nameservers: - ns3.server2.net (127.0.0.2) - ns4.server2.net (127.0.0.2) server3 with nameservesr: - ns5.server3.net (127.0.0.3) - ns6.server3.net (127.0.0.3) so i want to transfer all accounts from server1, server2, server3 to powerserver powerserver with nameservers: - one.powerserver.net (127.0.0.4) cluster DNS - two.powerserver.net (127.0.0.5) cluster DNS problem: DNS propagation if nameserver client change to new nameservers... i don't want to have dns propagation and avoid downtime i have big clients so every minutes downtime is problem so how i can make this happen? is it even possible? can i make this without changing nameservers? if i change namesrvers that is simple transfer accounts
