I tried to install data-migration tool for magento 2.1.0 from magento 18.104.22.168. After I typed in following commands:
(1) composer config repositories.data-migration-tool git https://github.com/magento/data-migration-tool
(2) composer require magento/data-migration-tool:2.1.0
I got following error message:
Your requirements could not be resolved to an installable set of packages.
- The requested package magento/data-migration-tool 2.1.0 exists as magento/data-migration-tool[2.0.0, 2.0.2, 2.0.5, 2.0.7, 1.0.0-beta] but these are rejected by your constraint.
Installation failed, reverting ./composer.json to its original content.
Could somebody help me about it? thanks a lot.
maybe that tool you uses is not compatible with your version of Magento. check cart migration guide again
In your case, I think you can clear all data and upgrade again with magento 2 upgrade steps. Errors in migration process are general. However, we try to avoid serious problems.
Can I get your current website URL for review ? once I review, I will help you how to migrate properly.
