• Disseminators (disseminator datastreams will be migrated, but they will no longer function in Fedora 6)
• Redirect (R) and external (E) datastream content (URLs will be copied)
• Solr index
• Resource index
• XACML policies (objects with POLICY datastreams attached will be migrated, but they will no longer control access in Fedora 6)

Prerequisites

• A host machine with filesystem access to both the Fedora 3 disk storage (or exported FOXML files) and the target OCFL disk storage.
  The target allocated disk space should be roughly the size of your Fedora 3 repository occupied disk space.

  Note:

  Note
  OCFL repositories typically contain many small files, so the allocation block size of your filesystem can make a difference. We recommend using relatively small allocation block sizes if possible to avoid excess bloat in your migrated content.

  
  

  Note

  The migration to Fedora 6 will create ~4 files per datastream, with additional files for versions and what is required by OCFL. If you have a large Fedora 3 repository with many datastreams, you should consider using a filesystem which allows for large amounts of files such as XFS, ZFS, or Btrfs. Filesystems which rely on a fixed inode table, such as ext4, may run out of inodes for files and cause the migration to fail. If you anticipate this could be an issue, talk with you system administrator to find a solution which works for your repository.

  
  

• Java 11 installed on the host machine.
• Knowledge of the Fedora 3 filesystem layout (legacy or Akubra), if migrating directly from Fedora 3 data on disk.
• Familiarity with the command line:  examining files and directories, running commands, redirecting output of commands to files, the grep utility, etc.
