Change of URLs from VB4 to VB5 lead to thousands of 404 errors

[sergioloporto]

Hello, since when I upgraded from vb4 to vb5 connect I noticed that there is a huge increase of 404 error in Google Search Console. This increase is more than 3000%

Here some examples of url changes:

http://site.com/list/category/74-category-name (for this url I could not find the new one)
Here you find many examples of "list" in urls that after upgrade to VB5 they will give a 404:

Also the links to the forums are now different. In VB4 it was:

http://site.com/forums/19-name

and after upgrade it should be:

http://site.com/forum/mama-forum/name

Also this one changed URL:

http://site.com/members/1003-name

should be

http://site.com/member/1003-name

Can you please explain why there are such url changes?
Is there an official fix for it? Or a bug open?
Is the only solution to redirect/rename the URLs in (htaccess/virtualhost)? If yes can you please provide the code that makes the workaround for it?

Thanks in advance
