[xwiki-devs] [New extension request] Class migrator application

Hi devs, I would like to start a new contrib extension called application-class-migrator. What is it? If you want to maintain an application, you might need to perform some migrations on the data structure used by the app (rename xproperties, add some, remove some, refactor some, …). The idea of this application is simply to provide a user friendly solution for application developers to handle migrations. Those migrations can be described in a specific XObject in a page. The migrations will be executed on extension upgrade. I'll take care of creating the repo and the project on JIRA. Thanks, Clément
