Drupal Multi-Domain Site Maintenance

The Domain Access module is a very complex addition used by several of our clients, and it introduces quite a bit of complexity when it comes to testing updates, in addition to requiring some custom patches.

Compared to running a site with several multi-sites, however, it's a good way to go because it allows you to share much of the same content, configurations, workflows, and more across all of your sites.

With Domain Access, we charge a higher rate for the overall Drupal maintenance, but because there is only one shared database across all of them, there's no additional per-domain charge -- this rate covers however many domains you have.
