Upgrade Steps

For Manual Installations

Pre-upgrade steps

  1. Ensure section_list migration has been run (See https://samvera.atlassian.net/wiki/spaces/AVALON/pages/2580086785/Upgrading+Avalon+7.7+to+Avalon+7.8#MediaObject-Section-List-Migration)

  2. Export Fedora 4 repository and migrate it to Fedora 6 OCFL

    cd /tmp
mkdir fc4_to_fc6
cd fc4_to_fc6

# Setup Java 21+ (if needed)
curl -O -L https://download.java.net/java/GA/jdk21/fd2272bbf8e04c3dbaee13770090416c/35/GPL/openjdk-21_linux-x64_bin.tar.gz
tar xvzf openjdk-21_linux-x64_bin.tar.gz

# Download specific version of import/export tool
curl -O -L https://github.com/fcrepo-exts/fcrepo-import-export/releases/download/fcrepo-import-export-1.2.0/fcrepo-import-export-1.2.0.jar

# Export from fedora 4
jdk-21/bin/java -jar fcrepo-import-export-1.2.0.jar -b --dir fcrepo4.7.5_export --user fedoraAdmin:fedoraAdmin --mode export --resource http://fedora:8080/fedora/rest --binaries --membership --auditLog > importexport_`date +%Y%m%dT%H%M%S`.log 2>&1

# Download specific build of upgrade-utils

# Run migration Fedora 4 -> Fedora 5 (inside container again)
jdk-21/bin/java -jar fcrepo-upgrade-utils-6.4.0-SNAPSHOT.jar --input-dir fcrepo4.7.5_export --output-dir fcrepo5_export --source-version 4.7.5 --target-version 5+ > upgrade_5_`date +%Y%m%dT%H%M%S`.log 2>&1

  3. Setup Fedora 6 (See https://wiki.lyrasis.org/display/FEDORA6x/Deployment )

  4. Copy migrated Fedora 6 OCFL directory to fcrepo.home and restart Fedora

Upgrade steps

  1. Install ruby 3.3.x (if needed)

  2. Update gems, and migrate DB

    bundle install --with production --without development test 
RAILS_ENV=production bundle exec rake db:migrate

  3. Install node.js 20.x (if needed)

  4. Update JS dependencies

    yarn install # in Avalon root dir

  5. Update configuration, see Config changes above

  6. Restart passenger (if using)

    passenger-config restart-app

For Docker Installations

Before upgrading an AWS docker install based on avalon-terraform or the aws_min branch of avalon-docker make a backup of your supplemental files prior to destroying the avalon container!

docker cp avalon-docker-aws_min_avalon_1:/home/app/avalon/storage ./active_storage_backup

Then load them into an S3 bucket:

aws s3 cp active_storage_backup/* s3://${SETTINGS__ACTIVE_STORAGE__BUCKET}/ --recursive

See https://github.com/avalonmediasystem/avalon-docker/issues/77 for more discussion on this. If you run into any problems, please reach out on slack or the email list.

Pre-upgrade steps

  1. Ensure section_list migration has been run (See https://samvera.atlassian.net/wiki/spaces/AVALON/pages/2580086785/Upgrading+Avalon+7.7+to+Avalon+7.8#MediaObject-Section-List-Migration)

  2. Export Fedora 4 repository and migrate it to Fedora 6 OCFL (inside avalon container)

    cd /tmp
mkdir fc4_to_fc6
cd fc4_to_fc6

curl -O -L https://github.com/fcrepo-exts/fcrepo-import-export/releases/download/fcrepo-import-export-1.2.0/fcrepo-import-export-1.2.0.jar

# Export from fedora 4
jdk-21/bin/java -jar fcrepo-import-export-1.2.0.jar -b --dir fcrepo4.7.5_export --user fedoraAdmin:fedoraAdmin --mode export --resource http://fedora:8080/fedora/rest --binaries --membership --auditLog > importexport_`date +%Y%m%dT%H%M%S`.log 2>&1

# Download specific build of upgrade-utils

# Run migration Fedora 4 -> Fedora 5 (inside container again)
jdk-21/bin/java -jar fcrepo-upgrade-utils-6.4.0-SNAPSHOT.jar --input-dir fcrepo4.7.5_export --output-dir fcrepo5_export --source-version 4.7.5 --target-version 5+ > upgrade_5_`date +%Y%m%dT%H%M%S`.log 2>&1

# Run migration Fedora 5 -> Fedora 6
jdk-21/bin/java --add-opens java.base/java.util.concurrent=ALL-UNNAMED -jar fcrepo-upgrade-utils-6.4.0-SNAPSHOT.jar --input-dir fcrepo5_export --output-dir fcrepo6_export  --source-version 5+ --target-version 6+ --base-uri http://fedora:8080/fedora/rest > upgrade_6_`date +%Y%m%dT%H%M%S`.log 2>&1

  3. Copy migrated data out into new fedora_data directory (outside avalon container)

    docker cp avalon-docker-avalon-1:/tmp/fc4_to_fc6/fcrepo6_export fedora_data

Upgrade steps

  1. Stop Avalon

    docker-compose down

  2. Update new code from avalon-docker

    git checkout main
git pull

  3. Pull new images

    docker-compose pull

  4. Setup fedora 6 cache database

    docker-compose up db -d
docker-compose exec db /bin/bash /docker-entrypoint-initdb.d/init-fedora-cache-db.sh
docker-compose down

  5. Check config changes then restart the Avalon containers

    docker-compose up

You can also build your own image, Docker Buildkit is recommended

docker-compose build avalon
