New site is located in a directory below public-html so public_html/dev.
Primary domain was pointed at this directory via .htacess in public_html
A directory containing all old site page file names created in dev directory, so public_html/dev/Pages.
Using WordPress module, old urls have been added to Redirection:
The dummy old page opens but doesn't redirect.
Is it something to do with the .htaccess file either located at the root or in the dev directory? Or is it that the old page files are empty and need some content for the WP redirect to work?
