See What's New in Avalon 6.1 for more details.
Upgrade to using Database-backed Noid ID Minter
Avalon 6.1 switched to using a database-backed noid id minter by default since it is more robust and recommended by the active_fedora-noid gem.
Set up the DB for minter state
bundle exec rake db:migrate
Backup your minter state file (default location is /tmp/minter-state). Skip if you do not have one.
cp /tmp/minter-state /tmp/minter-state.bak bundle exec rake active_fedora:noid:migrate:yaml_to_marshal bundle exec rake active_fedora:noid:file_to_database # Remove the minter state file rm /tmp/minter-state
If the following command runs without any output then it was successful
bundle exec rails r "MediaObject.new.assign_id"
Post-Upgrade steps
# Add a Fedora4 record identifier to existing MODS record bundle exec rake avalon:migrate:record_identifier
