# Upgrading Nix
|
|
|
|
> **Note**
|
|
>
|
|
> These upgrade instructions apply where Nix was installed following the [installation instructions in this manual](./index.md).
|
|
|
|
Check which Nix version will be installed, for example from one of the [release channels](http://channels.nixos.org/) such as `nixpkgs-unstable`:
|
|
|
|
```console
|
|
$ nix-shell -p nix -I nixpkgs=channel:nixpkgs-unstable --run "nix --version"
|
|
nix (Nix) 2.18.1
|
|
```
|
|
|
|
> **Warning**
|
|
>
|
|
> Writing to the [local store](@docroot@/store/types/local-store.md) with a newer version of Nix, for example by building derivations with [`nix-build`](@docroot@/command-ref/nix-build.md) or [`nix-store --realise`](@docroot@/command-ref/nix-store/realise.md), may change the database schema!
|
|
> Reverting to an older version of Nix may therefore require purging the store database before it can be used.
