Google has a change of address feature in Google Webmaster Tools, they also have detailed instructions on how to move a site but it seems like they want to do more to help webmasters who want to move their sites.
Google's Pierre Far posted on Google+ a question to webmasters asking them "what confuses or annoys you about moving your site?"
Google is looking to hear from you all about what they can do to improve the process.
Pierre added:
What would be your wish list for (say) Webmaster Tools or Google's indexing systems to help you? I want to know!Let's define site moves properly as there are many kinds (and they're all in scope for this question :) ):
1. Site moves without URL changes. Here you change the underlying CMS or move to a different hosting provider without changing anything visible to users.
2. Site moves with URL changes. Here you're moving from HTTP to HTTPS URLs, or moving to a different hostname, or the paths of the URLs change (e.g. from example.com/page?id=1 to example.com/foo).
We're NOT talking about site redesigns.
So here is your chance to give Google feedback early on as they look to improve Google Webmaster Tools in this area.
Oh, clearly Google did not say they are building anything but you have to read between the lines.
