Many website owners will upgrade their version of Drupal to make the maximum of new features. If you too have reached the same decision for your website, here are step-by-step instructions to assist you in the drupal migration process:
First, it is important to understand that an update from Drupal 6 to Drupal 7 is one of the main because there are significant differences in how the two versions use and store data. If your website is not too complicated, and you have backed up your core data at regular intervals (as recommended by the developer), the process must not be too tricky for you.

2. So now that you are ready for it, the first step in the process of upgrading your Drupal is to back up your site database. There are some tools that are easily available online that can help you in this process. Or, if you prefer to perform backups manually, you can use phpMyAdmin.
3. After backing up your database, you also need to back up all files and folders to a secure location. It could be your PC, your hosting control panel, or simply an online server separately.
4. You need to check the status of your contributions and custom modules to ensure that you go through the process of updating the entire work. Check the drupal.org Drupal website for information on upgrading your modules.
