This documentation is a work in progress.
Data from your R5 database will be loaded directly into your R6 database then migrated for R6 in a later step. Role_map data will be needed in R6 for the Fedora migrate step, so it needs to be imported first.
# This example is for mysql. Adjust as necessary for your R5 database mysqldump -u avalonweb -p avalonweb --no-create-info --complete-insert --tables annotations api_tokens bookmarks courses identities ingest_batches playlist_items playlists role_maps users > /tmp/avalon.r5.dump.sql
If you are a developer wanting to test your migration on sqlite locally...
Sqllite3 doesn't like mysql dump files so a transformation script needs to be run on it. Download https://raw.githubusercontent.com/dumblob/mysql2sqlite/master/mysql2sqlite, make it executable, and run it on the dump file.
".read" returns "memory", which is good.
SSH into your r6 box, wipeout the database, and load the R5 database dump.
# ensure that Fedora, Solr, and the DB are clean # it will ask you to verify the targets are correct bundle exec rake avalon:wipeout #go into the database console and import sqlite data bundle exec rails dbconsole mysql> source /tmp/avalon.r5.dump
Add yourself back in as administrator in the rails console
bundle exec rails c > g = Admin::Group.find('administrator') > g.users += ["firstname.lastname@example.org"] > g.save!
Rails won't use your newly imported role_map data unless you clear it from cache.
bundle exec rails c > Rails.cache.delete("RoleMapHash")
SSH tunnel or open up your fedora3 server to your new Avalon app:
# Choose an available local port to use as a mirror of your fedora3.host:8983 import source # In this example 9999 is used. It must match the port used in fedora3.yml in the next step ssh -L 9999:localhost:8983 email@example.com
keep the ssh mirror running in another tab as you do the next steps.
The fedora3.yml should work without change, but if you do have trouble, here's an example fedora3.yml for the avalon demo server.
development: user: fedoraAdmin password: <password> url: http://localhost:9999/fedora test: user: fedoraAdmin password: <password> url: http://localhost:9999/fedora production: user: fedoraAdmin password: <password> url: http://localhost:9999/fedora
Run the migration! You can watch it run on your target avalon by going to <your avalon url>/admin/migration_report .
bundle exec rake avalon:migrate:repo
After this command is finished, look through the report and see which items have failed and troubleshoot using the errors listed.
# Run script to map fedora 3 pids in database to newly minted fedora 4 noids bundle exec rake avalon:migrate:db
#This will delete any bookmarks that point to failed items bundle exec rake avalon:migrate:bookmark_cleanup
