Upgrade 1.4.0 to 1.6.0

I’m looking for an advice on how to migrate older operator to latest

  1. I guess there is no way to do it automatically, correct me if I’m wrong?

  2. Would you map same storage volumes and submit new yaml files for Kubernetes where images are bumped to 1.6.0? Or easier/possible option is to start from scratch?

  3. If starting from scratch in a new storage, would you worry about backup error that I’m getting here?

> root@mattermost-backup-0:~# mysqldump -h mattermost-cluster-proxysql -u root -p$pw --single-transaction --routines --triggers app | head -n 5
> mysqldump: [Warning] Using a password on the command line interface can be insecure.

> mysqldump: Got errno 32 on write

P.S. I’m able to see latest records in SQL backup file and size is about right. As you see, I don’t use public cloud, for instance S3.
