FreeNAS boot disk failure and want to recover old data

[Sa Hein]

My FreeNas Stick I'm currently using and it can't boot anymore. My two physical data pool HDDs are mirrored. Those two are considered to be good. So, how can I recover the data from the current old HDD’s data? I understand that it will be fine if I reinstall the current Boot Stick fresh and import the original pool again. However, I'm currently using FreeNAS and the new version is TrueNAS. In that case, I wonder if it is possible to import the old HDD again. Also, I didn't save the previous version config file.

Thanks

Yes, you can do that, the pool should import with no issues if it's healthy.

Just note that you're importing a pool, not a disk (that's another function for importing from non-ZFS disks).
