One of the sites I support is moving to a new host and a new redesign next week.
The current site has been running a Google Custom Search Engine, and will be on the redesigned site.
The old/current site is going to be moved to a sub-domain for archival purposes: archives.mywebsite.com, and that'll need to be indexed going forward as well.
The question is how to handle the cutover.
Do I have to do anything specific in regards to telling Google to use the 'new' site index instead of the old?
Do I have to go into Google Webmaster Tools and re-verify mywebsite.com and archives.mywebsite.com?
Thanks in advance!
