can I change the DNS info at the registrar so that I use

ns1.oldhosting.com
ns2.newhosting.com

and let that propagate for say 3 days then change it to

ns1.newhosting.com
ns2.newhosting.com

or am I going about this the wrong way and if so how do I avoid a site being unreachable during propagation?
