Performing an upgrade for a Drupal site from one version to the other can be a daunting task, fraught with many surprises.
We have a proven methodology for doing such upgrades, even if you are 3 releases behind the latest stable release!
We get a copy of your site, and scope the amount of work needed. After getting approval for the cost estimate, we proceed to do the upgrade on our copy of the site, then give you access to test it out.
Then we schedule the actual live site upgrade with minimal downtime for visitors.
