Because I haven't done this in a while, want to make sure I'm remembering correctly. In our datacenter, I have an ASA with a /29 on the outside interface that connects to a cisco 4508 that is it's default gateway. We need to expand our subnet to a /28. If I remember right, the DC should be able to change their switch SVI to a /28 first without interrupting traffic then I should be able to change the subnet on the ASA without interrupting traffic. Is this correct?
