To walk this migration path you will need to download and run the migration-utils tool directly against the on-disk representation of your Fedora 3 repository. In other words it is not necessary to export your Fedora 3 repository. The fcrepo-migration-utils will not make any changes to your Fedora 3 repository so it is not necessary to make a backup before starting. You will need to make sure that you have sufficient storage space available in the target directory as the migration will effectively create a copy of your Fedora 3 repository in the Fedora 6 format which conforms to the Oxford Common File Layout (OCFL) specification. Once your Fedora 3 repository has been migrated to Fedora 6, you must start up an instance of Fedora 6 on top of the newly created OCFL. As Fedora 6 starts up it will automatically rebuild internal indices by scanning the OCFL. This index initialization can take a few seconds or several hours depending on the size of your repository.
Download the latest version of the migration-utils utility: https://github.com/fcrepo-exts/migration-utils-4.4.1-SNAPSHOT-25cdf-driver.jar/releases
- Follow the instructions in the migration-utils README: https://github.com/fcrepo-exts/migration-utils
Start up Fedora on top of your newly created Fedora 6 OCFL-compliant repository using the -Dfcrepo.home configuration property.
