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)
