1.3. Upgrading from JBoss Data Grid 6.4.x to 6.5

The following methods were introduced in Red Hat JBoss Data Grid 6.5 for the AdvancedCache and RemoteCache interfaces, and both of these methods have performance increases when sets of data are placed or retrieved versus the similar operations performed sequentially. This allows bulk large sets of data to be retrieved and placed more efficiently. This difference is especially significant in server-client mode and as the number of transferred items increase; however, there is additional memory overhead during the transfer itself as the full set must be loaded into memory.

Overloaded versions of these methods exist; documentation on these methods may be found in the Red Hat JBoss Data Grid API Documentation.

A migration tool has been created which converts the data stored in a JDBC store by Red Hat JBoss Data Grid versions 6.0 and 6.1, which used Infinispan 5.2.x, into the format used by versions 6.2 and later, which use Infinispan 6.x.

This tool will function for all JDBC store types:

If any custom marshallers were used these need to be provided on the classpath when the tool is executed, for instance:
