• Recommended tasks during the installation phase:  

1. 1. Test the database connections;
   2. Check System property Kie Persistence to ensure database endpoint is correctly configured with the corresponding dialect:

<property=org.kie.server.persistence.ds[…]/>

< property=org.kie.server.persistence.dialect[…]/>

3. Check the Maven version;
4. Check if there are any deprecated libraries (It is possible to check it by looking for warnings on the application log);
5. Check config files to ensure all endpoints are correctly configured focusing on the following properties on the system property section on this path: /target/jboss-eap-7.4/configuration/standalone/standalone-full.xml (Check which standalone file are you using):

<property name="org.kie.server.controller" value="http://<endpoint>:8080/business-central/rest/controller"/>

<property name="org.kie.server.location" value="http://<endpoint>:8080/kie-server/services/rest/server"/>

6. Check the execution of business assets contained in the migrated business application: simulate decisions, validate responses, and make comparisons between the new application version (migrated) and the previous version (before migration).
