We're considering upgrading from shared to VPS, and I'm wondering what the upgrade experience is like?
DH claims that there will be no downtime or glitches... but it's hard for me to picture how that could work and there isn't any information on how it works under-the-hood (which leaves me a little worried). We'd be upgrading both the web and mysql server. Also, they say it'll happen sometime in the next "day or so" - which is longer than we'd like to have an outage window.
Does anyone have experience upgrading from shared to VPS? Is it really as seamless as DH claims? How does it work?
Thanks in advance!
