Just a reminder so people don=E2=80=99t run away ;-): the upgrade story got=
 much
better shortly before 0.15.0, when =E2=80=98guix pull=E2=80=99 got the abil=
ity to =E2=80=9Cbuild
Guix from Guix=E2=80=9D in a way that does not rely* on the currently insta=
lled
Guix.  For example, you can run 0.15=E2=80=99s =E2=80=98guix pull=E2=80=99 =
and upgrade to
today=E2=80=99s Guix without problems.

Ludo=E2=80=99.

* More specifically, =E2=80=98guix pull=E2=80=99 relies on a small subset o=
f Guix
  functionality that hasn=E2=80=99t changed in a couple of years, which is =
a lot
  given Guix=E2=80=99s history.
