# Upgrading
This document covers upgrades for the 0.3.0 series and up. If upgrading from previous versions, we recommend [a fresh install](http://progrium.viewdocs.io/dokku/installation) on a new server.
> As of 0.3.18, dokku is installed by default via a debian package. Source-based installations are still available, though not recommended.
## Dokku
If dokku was installed via a debian package, you can upgrade dokku via the following command:
```shell
sudo apt-get install dokku
```
For unattended upgrades, you may run the following command:
```shell
sudo apt-get install -qq -y dokku
```
If you have installed dokku from source, you may run the following commands to upgrade:
```shell
cd ~/dokku
git pull --tags origin master
# continue to install from source
sudo DOKKU_BRANCH=master make install
# upgrade to debian package-based installation
sudo make install
```
All changes will take effect upon next application deployment. To trigger a rebuild of every application, simply run the following command:
```shell
dokku ps:rebuildall
```
## Buildstep image
If dokku was installed via a debian package, you can upgrade buildstep via the following command:
```shell
sudo apt-get install buildstep
```
For unattended upgrades, you may run the following command:
```shell
sudo apt-get install -qq -y buildstep
```
In some cases, it may be desirable to run a specific version of buildstep. To install/upgrade buildstep from source, run the following commands:
```shell
cd /tmp
git clone https://github.com/progrium/buildstep.git
cd buildstep
git pull origin master
sudo make build
```
