Hi
As you descibe withon documentation,
4SEF can import both sh404SEF configuration and SEF URLs while
Yes. And you said, twice:
> What I get out of this was, that meta data as title and description will be retransferred to Joomla files
> There I found out, that meta title and meta description of sh404SEF are transferred to Joomla fields.
meta data (title, description) are not transferred at all. 4SEF does not import them or do anything with them.
while upgrading from sh404SEF. My exact question is: what happens with the other data from sh404SEF that SEF-Urls, such as meta title and meta description and OG image information also stored by sh404SEF?
Nothing happens. 4SEF does not import or do anything with them.
As I replied above:
> You may have tried 4SEO maybe?
So 4SEO can import custom metadata you may have created manually in sh404SEF. As usual, this is described in details, on this page of 4SEO documentation.
