Hello,
it’s my impression that due to the way the distribution is put together, it’s easier to reinstall with a new image.
Remember to backup your home-folder and the .conf-files you made changes to.
The naming convention got changed between the two versions (here’s a post).

(130 or 13.0 [refer to FreeBSD version number] is still a greater version number than 1.4 
, but I can definitely see the risk for misreading! -and I might have done the same, if I arrived at the project today)
Have a nice day
Ludensen, a happy NomadBSD-user
