No. Oracle Approvals Management (AME) is to define approval rules that determine the approval processes for Oracle applications. The Workflow module uses this information for sending notification to the approvers based on the rules defined in AME
Will Oracle provide a Migration Tool from ebiz workflow to BPEL?
BPEL does everything that Workflow can do, but there is no migration tool to take a workflow process and convert to a BPEL process, like oil and water, so BPEL processes have to be built from scratch
In the future, is BPEL going to replace Oracle Workflow with in E-Business Suite?
No, Workflow will not be replaced by BPEL inside E-Business Suite. BPEL is used in Fusion Applications for business process orchestration and integration needs

Why do some workflows need workflow background processes and some don't?
Depending on the design as some item types need to execute functions which have higher cost so these functions should be deferred and execute later.
This will be happen by the workflow background process. Also if the design has an activity, which is relative to time and the time, has passed the activity is now marked as NOTIFIED by the Workflow Engine, this requires the workflow background process to execute it. Also if the design has a stuck process, which has a status of ACTIVE, but cannot progress any further
