TrueNAS updates system software from the System > Update screen. Updates can be installed from the update server or by uploading a local update file.

Update profiles control which TrueNAS releases the system checks for updates. Community Edition systems default to the highest profile available for the installed version. For example, a fresh install of a General release defaults to the General profile.

TrueNAS Enterprise systems ship with the Mission Critical profile set by default. Enterprise users can select General or Mission Critical only.

After you download the .iso file, you can start installing TrueNAS!

This article describes verifying the .iso file, then installing TrueNAS using that file, and selecting the type of installation as either on physical hardware or a virtual machine (VM).
