Upgrade to Trixie Unstable? (staging)

[biketool]

This is my /etc/apt/sources.list (I added a #commented out my added staging line until ready to use)

Code:

deb http://ftp.debian.org/debian trixie main non-free-firmware
#deb http://ftp.debian.org/debian staging main non-free-firmware

but there is also /etc/apt/sources.list.d/mobian.list which  also needs a line for staging so did same as above

Code:

deb http://repo.mobian.org/ trixie main non-free-firmware
#deb http://repo.mobian.org/ staging main non-free-firmware

does this look good to switch sources to staging and run sudo apt update && sudo apt dist-upgrade?

I tested my upgrade surces.list for upgrade, doesnt work... 404 Not Found
Any ideas?
