Fedora export / import

In sufia 6 instance:

$ bundle exec sufia_export --models GenericFile=Chf::Export::GenericFileConverter,Collection=Chf::Export::CollectionConverter

• Open up fedora port to the other server so it can grab the binaries

Change all the 127.0.0.1 URIs to reflect actual host, e.g.

$ find tmp/chf-import -type f -name "*.json" -print0 | xargs -0 sed -i "s/127\.0\.0\.1/dev6.hydra.chemheritage.org/g"

Move the resulting directory full of exported data from tmp/export to the new server's tmp/import (or wherever desired; this can be provided to the import script)

On sufia 7 instance:

• configure sufia6_user and sufia6_password in fedora.yml

$ bunx sufia_import -d tmp/chf-import --json_mapping Chf::Import::GenericFileTranslator=generic_file_
