The release of Hybrid Data Pipeline 5.0 includes two updates that impact the upgrade process. First, a JRE is no longer included in the Hybrid Data Pipeline product package. Second, Hybrid Data Pipeline has dropped support for OData Version 2.

Note: Hybrid Data Pipeline 5.0 server is backwards compatible with the 4.6 On-Premises Connector, ODBC driver, and JDBC driver. However, the 5.0 versions of these components cannot be used with the 4.6 version of the server

With the removal of the JRE from the product package, you must take two main actions before upgrading when using the server installer. First, before running the installer, you must have a compatible JVM installed on the host machine and defined on the system path. Second, during installation, you must specify the path to a compatible JVM to be used by the server at runtime. The JVM used by the server may be different from the one used by the installer. Note that the server installer removes any existing, embedded JRE during installation. For information on JVM requirements, see Product requirements.

With the removal of OData Version 2 support, OData Version 2 data sources must be replaced with OData Version 4 data sources. Replacing these data sources involves (1) removing the OData v2 data sources and (2) creating OData v4 equivalents. In turn, any data source groups configured with OData v2 data sources must be recreated as OData v4 groups. In addition, your OData application must be modified to use OData v4 and the OData v4 data sources.
