Moving our sites to a new ip

Moving our sites to new ip w/o losing ranking

[EAHunt]

It has been forever since I have posted to Webmaster, started getting busy with software dev. Anyway, my partner hosts our "ranked #1 in google" website. We are moving our co-location for servers to new company and don't want to lose ranking. Last time we changed ips we were gone for 3 months. This would kill us, anyone got any ideas.

If it were me, I'd leave the old site where it is and create a new domain on the co-loc server. Once the new domain (hopefully with new content) is ranked, you can redirect from your old site.

If you have to move, don't change the site or whois data. Keep everything as stable as possible.
