FreeNas Server to TrueNas Server

I need some assistance to be sure I don’t mess up and loose any data. My current set up is running FreeNas version 11.3.U5 mainly for a media server with 1 Pool with a total data of 3.5 TB. Not sure if it’s set up in any particular Raid.

I would like to move it over to the new server in the most streamed line way without the risk of losing data and still set up the way I currently have if possible with Plex.

Should I change to a certain Raid format? Also the new server has 3 HDDs that are not part of the current Pool.

Thank you

You should look at the UI to understand the system…

You can then follow the update path… one version at a time

Upgrade to 12.0 → 13.0 → 24.10

It should keep your data intact…
