Business Objects 4.2 Server Migration

Hello,

we are running one Windows Server 2008 R2 Server with Business Objects Server 4.2 Server on it. The Database is a Microsoft SQL Server 2014.

Now we need to migrate the Business Objects Server 4.2 from the Windows Server 2008 R2 to a Windows Server 2019 with Desktop Experience and switch off the old Windows Server after the Migration

I searched about this Scenario but i'am not sure how to do this without any Damage to the BO Enviroment.

Can somebody help me with this?
