I am upgrading and moving to a bigger, better server. This may be an old question I missed in the past, but will this affect my pages inexed in Google? My IP will be changing. In terms of the Search Engine, should it be a non-event changing servers?
Do I need to do anything special as far as the search engines?
Galtego - would running 2 servers with the same content not be classed as Mirrored sites?
We had both servers running .... but only until we new the sites worked perfectly on the new server. So it was for tech reasons rather than SE reasons. I think both servers were running at the same time for less than a day.
I don't know the answer to the above question - it was purely a thought i had when i read your comments.
They won't be seen as duplicates because each entity (person or spider) will view the site as one thing based on the domain name, not the IP numbers. I have seen regular Googlebot take up to two weeks to completely resolve the domain name to the new IP number - and the AdSense bot (MediaPartners) take up to three weeks to move completely over to the new IP. All the while, even with two IP numbers, it is only one site - no duplicate content penalty. The overlap is to be sure that the spiders resolve the domain name properly.
