Upgrading SingleFileStore from 8.x to 9.0.x

[joe.trewin]

Hi,

We're beginning the process of upgrading a system that uses Infinispan 8.0.3 to 9.0.3 in embedded + replicated mode where one node persists data in a number of SingleFileStores, using custom Externalizable implementations.

The upgrade notes point out that the marshalling system has changed and points users in the direction of the JDBC store migrator tool, but there's no mention of how one might upgrade a different type of store; in our case SingleFileStores.

Two options spring to mind - attempt to create a tool, maybe using the JDBC migrator as a starting point; or failing that a more manual tool that writes the data to some intermediate format and another tool that'll then read it in and store it.

Has anyone done this, or is there any process that I've not yet found?

Thanks for any help.

There are currently no plans to create a migrator tool for store types other than JDBC. However for your use case I recommend that you take advantage of Infinispan's rolling upgrade capabilities; ensuring the target store is configured with the required stores and externalizers.

Thanks for the help Ryan - we'll try that.
