Switching from Truenas scale to HEXos

[timvanhelsdingen]

Hey all,

I’m looking at HEXOS and thinking of giving it a try, but before I drop $199 I’ve got a few questions.

Current setup:

• TrueNAS Scale 25.04.2

• CPU: Intel Xeon Silver 4210 @ 2.20 GHz

• RAM: 64 GB

• RAIDZ2 pool: 8 drives, ~64 TB total (main archive)

• Mirror pool: 2 drives for Docker apps

Use case:
I’m a VFX artist and this NAS is my central hub:

• Stores my entire long-term project archive

• All workstation SSDs get mirrored here for backup

• Render nodes read/write directly to the NAS during jobs

• Constant file syncs via Resilio to 2 workstations + 1 backup NAS

Questions before switching:

• Will my ZFS pools import cleanly from TrueNAS?

• Will HEXOS detect my existing Docker containers, or will I have to rebuild them? (Reindexing Resilio takes forever, so I’d like to avoid that.)

• Will HEXOS mount my ZFS pools from HDDs without compatibility issues? (This is why I skipped Unraid — different ZFS version.)

I like TrueNAS and can handle technical setups, but I’d prefer something less high-maintenance that “just works,” especially for running apps. Too many Docker containers have broken after updates, so I’ve kept them to a minimum and rarely update them.

For anyone who’s migrated from TrueNAS to HEXOS — would this be a solid upgrade for my workflow?

I used to be able to give a confident yes before but im actually not sure. I think truenas scale 25 added some new flags to zfs pools preventing being used on machines running at the latest truenas 24 (which hexos is still based on).

hexos will be getting an update sometime in q3 that should bring it up to truenas 25. once that happens it will go back to a confident yes.

ofc i can be completely wrong about 25 update to zfs feature flags breaking compatibility with older os versions or misunderstanding it. I think it was a manual update too so if you didn't update it simplifies things.

i don't have enough experience on the matter to confirm any of your other questions. hopefully someone else can chime in with more info.

at this time a lot of hexos features have not been fully implemented. if you switch over now you will be seeing more of the same and having to deal with a lot of truenas stuff for apps because hexos only supports 2 apps for one click installs right now. Once the q3 update drops im expecting hexos to really ramp up with more 1 click install apps.
