Hi
however, I have many sites using sh404sef are we meant to manually redirect the URLS from sh404sef to joomla sef and port the meta over manually?
Depends if you actually mean "redirect". If you really mean redirect, then 4SEO already does that today: If you install it on a site where the sh404SEF database tables are still present, it will automatically redirect any sh404SEF URL to its Joomla SEF counterpart. This does mean the URLs on your site will change, although how many actually changes also depends on what type of content you have.
As for the custom meta data, if you have any, this will be imported into 4SEO, as 4SEF will not have any other function than dealing with SEF URLs. The importer will happen at about the same time that 4SEF is released.
I've read in places 4SEF is meant for this transition - is this available? When will it be available?
It's not meant to "transition" but to take over sh404SEF URLs creation and customization - either on Joomla or Joomla 4. All SEO features in sh404SEF are already available in 4SEO - and many more.
As for the timeframe, there isn't any official one. We do expect a first release, if only beta, for this quarter. Taking into account the numerous sh404SEF URL configuration option is proving to require quite a bit more work than expected.
