Truenas scale migration

[derekgaro]

I am trying to migrate from one server to another. I have upload my original truenas configuration file and set up a replication task to copy the data. Everything looks good on the new server besides the fact when I go to the apps selection, none of my apps are there. When I try to re-download apps I get the below error message.

[EFAULT] Kubernetes service is not running.

Oh, you tried to replicate the data over? I'm not sure all those storage/ix-applications datasetsts have snapshots on them that will have the data replicate properly... You can try going to Apps -> Settings -> Unset Pool, remove that storage/ix-applications dataset and then go back to Apps -> Settings -> Choose Pool to force it to re-init the Apps.

But before you do that, it may be worthwhile to open a ticket for us with a debug attached. This type of migration is something we may need to look further into to see how to better handle.
