Hibernate is an object-relational mapping (ORM) tool for Java environments. It provides a framework for mapping Java objects to relational database artifacts, and Java data types to SQL data types. It also provides the ability to query the database and retrieve data.

Reasons to Migrate
Reasons why you would want to migrate from Hibernate to EclipseLink include:
Performance and scalability: EclipseLink's caching architecture allows you to minimize object creation and share instances. EclipseLink's caching supports single-node and clustered deployments.
Support for leading relation databases: EclipseLink continues to support all leading relational databases with extensions specific to each. EclipseLink is also the best ORM solution for Oracle Database.
A comprehensive persistence solution: While EclipseLink offers industry leading object-relational support, EclipseLink also uses its core mapping functionality to deliver Object-XML (JAXB), Service Data Object (SDO), and Database Web Services (DBWS). Depending on your requirements, you can use one or more of the persistence services based on the same core persistence engine.
JPA Support: EclipseLink is the JPA 2.0 reference implementation, and it will support future versions of JPA.
