Zammad Migration


I’ve deployed zammad on EKS cluster using helm chart, i’m planning to move my cluster to a single AZ , as zammad doesn’t support EFS i used EBS as a storage class for my deployement .

my 2 PVCs have been provisionned in 2 AZs so i should delete them to be able to perform the migration .

If i delete the PVCs and move to a single AZ then redeploy zammad shoud be fine or i’ll lose my data ?
How to spesify a pvc in the helm chart values ?

  • Used Zammad version: 3.6.0
  • Used Zammad installation source: Helm chart zammad-3.4.0
  • Operating system: EKS v1.17
  • DB: RDS postgress

kubectl get pvc
zammad-zammad-dev-0 Bound pvc-xxxxx 15Gi RWO gp2 1d
zammad-master-zammad-master-0 Bound pvc-yyyy 30Gi RWO gp2 1d

Thanks for your help .

By default the docker-compose stores attachments within the database.
This means, as long as your database is fine you shouldn’t loose any data in theory.

I’d like to suggest to have a backup to be extra sure.
