Drupal 7 features an admin strip at the top of the pages available in previous versions only through the integration of separate modules. Site control has been incorporated into a series of shadowboxes, then further increase the ease of use. Good image support and function fields also improves the performance of Drupal 7. This version also solves one problematic feature of Drupal 6, which is the inability to simultaneously carry out the handling of personal files and CSS file aggregation.
To make the maximum of this new feature, many website owners will upgrade their version of Drupal. You can get more information about Drupal migration via browsing various online resources.
If you too have reached the same decision for your website, here are step-by-step instructions to assist you in the migration process:
First, it is important to understand that an update from Drupal 6 to Drupal 7 is main one, because there are significant differences in how the two versions use and store data. However, 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 should not be too complicated for you.
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 drupal.org Drupal website for information on upgrading your modules.
