Hi all, I'm looking into upgrading a VPS and the hosting company claims they cannot do it on the same physical node hence the IP's are going to change. I know nothing about how their network is configured so they might just being lazy or it may really be necessary and the newer server may even be located in a different datacenter. But the bottom line for me is that 10 sites with dedicated IPs and another dozen or so on one shared IP are going to have to have their IP addresses changed.
Does anyone see a potential for any ranking trouble because of multiple sites in my WMT account changing their IPs at once? Any particular issue to watch out for? Have you done IP change en masse before?
I would appreciate any input on the matter.
