This topic discusses how a contributing developer can update Adobe Commerce or Magento Open Source without reinstalling it. If you are not a contributing developer, see Perform an upgrade.

To upgrade if you are a contributing developer:

Log in to your server.
Switch to the file system owner.
Change to the directory where you cloned the application. For example,
```
cd /var/www/magento2
```
Save any changes you made to the composer.json file because the next steps overwrite it.
Create a backup of your composer.json file.
```
cp composer.json composer.json.old
```
Update your local repository to get the latest code:
```
git pull origin develop
```
NOTE

If git pull origin develop fails, see troubleshooting.
Diff and merge your composer.json.old file with the composer.json file.
Resolve dependencies and write exact versions to the composer.lock file.
```
composer update
```
Update the database:
```
bin/magento setup:upgrade
```
Clean the cache:
```
bin/magento cache:clean
```
