Looking for confirmation/guidance Core to Scale upgrade

[keithg]

I've been running TrueNAS for a while (since about 2014 ish) and have a pretty simple system at this time. NFS mounts, Plex, OwnCloud and a jail I run abcde in so I can rip CDs to the NAS on the NAS. All my systems are linux. Running FreeBSD was always a bit of a pain where whenever I needed to do something, I'd have to learn the FreeBSD way and try to figure it out.

I am building a new NAS from scratch and all I want to re-use are the pool drives. My previous system is old and slow (Intel(R) Xeon(R) CPU X5355 @2.66GHz + 32Gb ECC ram). It is missing some capabilities I need such as faster transcoding and virtual machines.
I have all the bits in hand and this will be a new from scratch build and I am leaning toward using using Scale for the linux compatibility/consistency. I want to import my ZFS pool form the Core to the new from scratch Scale. I will install Plex and OwnCloud and create a docker image for ripping from scratch as this should not be too hard.

Do I need to do anything to be able to import the ZFS Pool? From what I read, it seems that when Scale boots, it should just 'see' the pool and ask to import it. Do I need to create some sort of backup or snapshot or something so it imports properly?

Your Core ZFS pool will import easily into Scale. Make a backup of your Core configuration file, it's the smart thing to do.

My only warning would be to NOT UPDATE ZFS (zpools) FEATURES !!! you will get a warning message to update ZFS but do not because once done, you will not be able to pop your pool back into Core easily. You do not need to perform this update and it likely not provide you any benefits.

@joeschmuck Thanks for the comment. Am I to use the configuration file when I actually put the pool drives in the new system? How do I do it? Just boot it with the discs atttached then where do I go to load the configuration?

do you use encryption on the drives? If yes, then check if it's GELI or ZFS native. If it's GELI, you have to migrate to ZFS native before moving to SCALE (it's a FreeBSD feature).

You can restore your CORE config on SCALE and pool + shares should be imported. Or you can import the pool when the basic system is setup (to get a clean install)

No encryption on my drives. Thanks for the suggestion.
