Question on automating reporting services configuration in SQL Server 2019 ?

Hi,

SQL Server 2019 does not support seamless upgrade for SSRS - from following post it was concluded that report server configuration like setting web service url and web portal url, etc has to be done manually although report Server database can be re-used to save time and efforts. Pls correct me if my understanding is incorrect.

As configuration requires manual steps, there is a real danger that SQL Server 2014 upgrade could be delayed, even though Microsoft support would end soon. Is there a way to automate these steps somehow ? 

Appreciate your valuable insights !!
