I have WSO2 APIM version 4.1.0 running with the Oracle database and I want to update the service to the newest version 4.3.0.

I can’t find any clear instructions on how to do it on pages like https://apim.docs.wso2.com/en/4.2.0/install-and-setup/upgrading-wso2-api-manager/upgrading-api-manager/ or https://github.com/wso2/product-apim or similar.
The wso2am-vX.X.X zip package has the folder dbscripts but only with the script to create the database, not to update.

If I run a wso2 apim 4.3.0 control-plane service using the databases from 4.1.0 the service doesn’t run and gives multiple ORA errors from tables, fields, etc missing, so there are clearly changes on the DB.
I have researched for some time and still can’t find any reference to database scripts to migrate the databases when updating the version of wso2am apim.

Can anyone point me to the page or site where the migration script for the database is (4.1.0 -> 4.2.0 and 4.2.0 to 4.3.0)?
Does this scripts exist? Am I missing something in the documentation?

Update the oracle databases of wso2 apim 4.1.0 to the 4.3.0 version with success
