First of all, decision: do we migrate and then old points to new, or we make new point to old, change dns, and migrate?

→ we migrate then change dns

Backups: biggest data is the images DB. script is complete (docker-clone-volumes.sh, or native) – first stop myaegee

about stopping my aegee:

• static maintenance page

• Attention!!

  • people will be applying for SUs

  • and online question statutory

  • AND AEGEE.org/vote

• Time:

  • (stop the system), start maintenance page

  • backups 10' to say the most

  • file transfer time (should be fast because internal network)

  • restoring backups 10'

  • validation (HOW?)

    • read logs like crazy

    • sampling images

    • normal login and check around

  • startup docker on new

  • run the ansible on old → becomes “reassign IP from azure cloud”

things to not forget:

• run it once to create folder files etc

• .env file as part of the backup

• certificates: we can decide to migrate them (just in case) but it should be simpler to make traefik regenerate them

Commands

Backup: images (with basically a restore because we start the setup first)

OLD$ scp -R /var/lib/docker/volumes/myaegee_events-media/ prod:/home/grasshopper/myaegee_events-media
NEW$ sudo cp -R /home/grasshopper/myaegee_events-media/ /var/lib/docker/volumes/myaegee_events-media/

OLD$ scp -R /var/lib/docker/volumes/myaegee_statutory-media/ prod:/home/grasshopper/myaegee_statutory-media
NEW$ sudo cp -R /home/grasshopper/myaegee_statutory-media/ /var/lib/docker/volumes/myaegee_statutory-media/

OLD$ scp -R /var/lib/docker/volumes/myaegee_summeruniversity-media/ prod:/home/grasshopper/myaegee_summeruniversity-media
NEW$ sudo cp -R /home/grasshopper/myaegee_summeruniversity-media/ /var/lib/docker/volumes/myaegee_summeruniversity-media/
