Replace USB bootdrive by mirroring?

[RetroSpeC]

Hi Everyone. I have been a user of Freenas for several years and my first build with 0.7 is still running without any problems :)
This is my first post ever in the forum as i have still to encounter any "real" issues with Freenas.

I have recently started to phase out some of my old hardware and invested in some upgrades. I do know the proper path to upgrade or replace the
boot drive/s for freenas. I am hower really lazy at the moment and i searched the forum and did not find anyone mention my question.

At the moment my freenas boots from a usb stick and i will continue to do so as i had no real problems with it. I am in the process of replacing my usb
boot drive with a fresh new usb stick (sandisk cruzer Fit) Current setup is running from one usb only. And i thought i could just insert the new one and mirror
it from current usb and boot up the new one and install a second sandisk and do a mirror again. Are there any issues with this? Or must i do a fresh install?
I know an install is pretty fast and easy when exporting the config file. I do however want to keep the downtime at a minimum.

Just to clearify. this is not the one still running 0.7 It is one of my more recent builds with 11.2 alreadey running on it.

You can do this from either the GUI or the installer. See https://www.ixsystems.com/documentation/freenas/11.2-U4.1/system.html#mirroring-the-os-device and https://www.ixsystems.com/documentation/freenas/11.2-U4.1/install.html#performing-the-installation.

However, for USB devices you're better off just making sure you have a copy of your latest config handy and another USB stick handy to do a quick reinstall/restore config when the current USB stick fails. Mirroring USB sticks is a lot of unneeded wear on the sticks.
