Yes, thanks that would fix it! So my whole old site is redirected to my whole new site (with identical pages in + new ones too) – and then I could add in any redirects for old pages I’m not going to use in my new site (but are now copied into my new site) to other relevant/updated versions in my new site – and put this individual redirect code in my new site .htaccess file?
So for eg. if a page in my old site was this: www/mysite.com/page-one it would have first been redirected to my new site to here: www/mysite.com/newsite/page-one and then I’d redirect this outdated page to it’s shiny new version www/mysite.com/newsite/page-two in my new site .htaccess.
Is that the best way for individual outdated files?
