How to transfer SEO value to new domain?

[SEOMa3]

Have an ecommerce website ABC that is ranking good on SERPs. now, the brand name is changing from ABC to XYZ. All the products will remain the same. only brand name is changing.
Since the domain will also be changing from ABC to XYZ, i do not want to lose out the SEO value i currently have. how can i have a successful transfer from ABC to XYZ without losing my SEO value? XYZ will be going live soon and i need to make sure sure that i start ranking for the keywords which are currently ranking for ABC. both ABC & XYZ are co.uk websites

I don't think that much has changed since this was discussed in May 2010: [webmasterworld.com...]

Google has an official guide for this is well: [googlewebmastercentral.blogspot.com...]

Here is a 2008 thread on the same topic: [webmasterworld.com...]

Thanks for the references.

Matt Cutts has mentioned several times over the years that moving to a new domain goes much better if it is the same folder and file paths, and the same content on the new site as was on the old, with the correct 301 redirect from the old site to the new site in place, to confirm ownership.

Does this still stand true? As i had mentioned that the brand name is changing from ABC to XYZ, so if I keep the content the same by just replacing the brand name i.e. replacing ABC by XYZ, will that work? or shud the whole content be re-written?

I may sound dumb here but i did not understand this:

If you're changing your domain because of site rebranding or redesign, you might want to think about doing this in two phases: first, move your site; and second, launch your redesign.

Just changing on the pages but keeping everything else the same should be a small enough change that the Google still sees the content of the pages as being the same.

When they are talking about a redesign, they are talking about switching CMS systems, using a new template/skin, or applying different colors and designs. Again, if you are just re-branding without changing anything other than the name, I don't think it will be a problem.
