Manual available for Joomla 3 to Joomla 4?

Hello,

Is there a migration manual available for Joomla 3 to Joomla 4?

I am encountering a white screen when accessing my link on test site:
https://www.*****.nl/koor/nieuws/nieuwsbrieven-archief?view=frontlist&catid[0]=96

For example, on this site:
https://www.*****.nl/nieuws/nieuwsbrieven-archief

The following is appended to the URL: ?view=frontlist&catid[0]=96

I look forward to your response.

Best regards,
Ron
