Is there any good way to move a live, production switch from one rack to a second, nearby rack? The switch does have redundant power supplies, plus we have a HotPlug (http://www.wiebetech.com/products/HotPlug.php) so I wouldn't think that power should be an issue.

This is how it is done for a server without all the fancy stuff you have.
A switch would be more of a challenge, especially if the hosts connected to it do not have a redundant connection. Even if you don't have to power it off, you very likely would need to disconnect and re-route the data cables.
