We are currently working with finalizing of Migration tool. The main new features we have added to the migration tool is

• Targets EPiServer CMS 5 R2 instead of SP2
• Migration of external users/roles (that is users stored in EPiServer db)
• Oracle support (not fully functional in this RC)
• Changed Link migration so metadata such as PageChanged and PageChangedBy is not changed (link migration is also significantly faster)

Here is a RC of the migration tool, the release version will probably be available in a soon future (read weeks not months). However we would gladly take feedback on this RC.

Here is a draft of the tech note that will be published on episerver.world when the MigrationTool is released.
