Maybe someone can help me with this issue. Thanks.

Answer 1

magento/data-migration-tool 2.1.4 is only compatible with Magento 2.1. In order to upgrade to Magento 2.2, you need to update this to 2.2.0 as well.

The error message is saying you're trying to update magento/framework to 101.0.0 (for 2.2), but magento/data-migration-tool 2.1.4 is only compatible with magento/framework 100.1. It can't resolve that dependency conflict, so it fails out.

Try:

composer require magento/product-community-edition 2.2.0 --no-update
composer require magento/data-migration-tool 2.2.0 --no-update

Then

composer update
