The goal of this note is to see if the Service Level Migration is supported in a SOA environment.

WebLogic Server supports two types of Migrations:
1. Service Migration
2. Server Migration

1. WebLogic Server supports service-level migration the following Migratable Services:
- JMS-related Services
- JTA Transaction Recovery Service
- User-defined Singleton Services

2. WebLogic Server provides two separate implementations of the leasing functionality.

- High-availability Database Leasing - This version of leasing requires the availability of a high-availability database to store leasing information.

Note: The leasing table should be stored in a highly available database. Migratable servers are only as reliable as the database used to store the leasing table.
Note: XA data sources are not supported for server migration.

- Non-database Consensus Leasing - This version of leasing stores the leasing information in-memory within a cluster member.

Note: This version of leasing requires that you use Node Manager to control servers within the cluster. Node Manager should also be running on every machine hosting managed servers within the cluster.
