You've never apparently done many e-commerce sites on the high-end of things.I have.
You pretty much never "revamp" on the production hardware. Ever.
You pretty much never "try something" on the production hardware. Ever.
When you do upgrades you stage new hardware or new hot-pluggable hard disks with the whole new system on the disk. That way, if something goes wrong, it's relatively painless to do a fallback to the older system so you only have a minor outage of service.
When you're trying something (Testing, prototyping), it's done on a mirror image of the production system that's currently running- but isn't connected to it in any way. This way, accidents don't cause service outages.
Breaking either of those "rules" means you haven't really worked at that level before- and you're just one mishap away from an egg on face moment or a brown paper bag over the head moment. If it's this, that tells people that they're more amateurs than anything else. If it's just this, it doesn't instill confidence.
