How to migrate from 2.x to 3.7.1

[shashov]

Hello.

I'm fairly new to modeshape. I have an existing java application, that is using modeshape 2 . Modeshape stores data inside an oracle database. I want to migrate my application to modeshape 3.7.1. I've read, that the java code should remain the same, since JCR API standart haven't changed. I understand, that I need to replace my modeshape-config.xml with .json configuration file and infinispan configuration file. I have found json schema, but I don't understand how transform my xml configuration into json one. It seems like the elements are different.

Is it possible to use the same database for modeshape 3.7.1, that is used for modeshape 2? If it is, then where should I put connectionUrl for DB with modeshape's data inside .json configuration?

Is infinispan configuration mandatory?

Thanks

Alexey

No, you cannot use in 3.x the same database that you used for ModeShape 2.x. ModeShape 3 was completely rearchitected, and so the configuration files and storage mechanisms are very different. Yes, Infinispan configuration is required. Have a look at the documentation for the 3.x configuration files, some examples (look in the 'src/main/resources' directory of each module), and even some configs for some test cases.

Can you share your existing configuration (perhaps a sanitized version of it)? Are you embedding ModeShape in a Java SE application, or into a web app?

As mentioned on IRC, since the latest master has been updated to use Infinispan 4.0, use the modeshape-3.7.1.Final tag when browsing through the GitHub repos.

Thanks. It's much more clear for me now.
