Looking for some SEO/WordPress advice on this.
An older business website has closed down. The same owner now has a new business in the same field under a different brand.

Moving the products across via CSV is straightforward, but there are also around 500 blog posts on the old site.

Would it be better to:
transfer the existing blogs to the new website, update/rebrand them with the new company name and then submit the new URLs through Google Search Console, or
rewrite/recreate the blogs from scratch on the new site?

The old business no longer exists, but the content itself is still relevant to the same industry.

Main concern is preserving any SEO value without creating duplicate content or causing issues with Google.
What would be the best way to handle this?
