Which database table are the SEO URLS stored in oxid version 3.x

Hi all

We need to do redirect 301 from oxid 3.x to oxid 4.x. Can anyone tell me where this SEO URL’s are stored in OXID 3.x.x Database or Is there any solution to get all the shop urls of oxid 3.x that have to be redirected?I found no oxseo database table or seo related files in the code.

Thank you in advance

is there a special reason why you want to put the redirections “into” the shop?
you could use the common redirection with .htaccess,
