The migration checklist

Owned by Fabrizio Bellicano

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 5'

    • 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

Setup: ready the maintenance page

done already

Setup: make prod an alias to new prod

OLD$ vim ~/.ssh/config add prod with IP 51.144.111.184

Setup: startup the thing once

#NOTE: doesnt matter the .env NEW$ cd /opt/MyAEGEE NEW$ make start NEW$ docker rm $(docker stop $(docker ps -aq))

Setup: trying the backups of the nightly on the new one

skipped

Migration: stop on OLD

Backup: pictures (with basically a restore because we started the setup first)

OLD$ sudo scp -i /home/grasshopper/.ssh/id_rsa -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$ sudo scp -i /home/grasshopper/.ssh/id_rsa -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$ sudo scp -i /home/grasshopper/.ssh/id_rsa -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/

Backup: things

LOCAL$ scp my.aegee.eu:/opt/MyAEGEE/.env prod:/opt/MyAEGEE/.env

Backup: databases

OLD$ cd /opt/MyAEGEE OLD$ make backup OLD$ scp -r /opt/backups/backup-2024-04-27_1033.tgz prod:/opt/backups/

Restore: databases

NEW$ cd /opt/MyAEGEE NEW$ vim scripts-server/restore.sh # To edit the DB names NEW$ #make sure the folders are in the proper place NEW$ ./scripts-server/restore.sh

Bring it back up: reassign IP in azure
