If you are working on a live site, please take backup of your database and files.

Open your composer.json file. Under the require field, update the magento version to 2.2.0 as follows.

magento/product-community-edition": "2.2.0"

In your command line, enter the command to reset the sample data.

php bin/magento sampledata:reset

Now remove all the sample data modules from the composer.json file

"magento/module-bundle-sample-data": "100.1.*",
    "magento/module-theme-sample-data": "100.1.*",
    "magento/module-catalog-sample-data": "100.1.*",
    "magento/module-tax-sample-data": "100.1.*",
    "magento/module-customer-sample-data": "100.1.*",
    "magento/module-cms-sample-data": "100.1.*",
    "magento/module-widget-sample-data": "100.1.*",
    "magento/module-catalog-rule-sample-data": "100.1.*",
    "magento/module-sales-rule-sample-data": "100.1.*",
    "magento/module-sales-sample-data": "100.1.*",
    "magento/module-grouped-product-sample-data": "100.1.*",
    "magento/module-downloadable-sample-data": "100.1.*",
    "magento/module-msrp-sample-data": "100.1.*",
    "magento/module-configurable-sample-data": "100.1.*",
    "magento/module-product-links-sample-data": "100.1.*",
    "magento/module-wishlist-sample-data": "100.1.*",
    "magento/module-review-sample-data": "100.1.*",
    "magento/module-swatches-sample-data": "100.1.*",
    "magento/sample-data-media": "100.1.*",
    "magento/module-offline-shipping-sample-data": "100.1.*"

After saving the composer.json file, run the composer update command and at last, re install the sample data by entering the following command in the command prompt.

php bin/magento sampledata:deploy

Run the setup upgrade command and check your site.
