Adobe Experience Manager cost vs self-hosted Drupal

The first step in comparing costs is to separate what you pay Adobe for the software from what you pay for everything else. AEM is offered along three delivery paths: AEM 6.5 and AEM 6.5 LTS self-hosted or on Adobe Managed Services, and AEM as a Cloud Service on a subscription with continuous updates and Edge Delivery Services, according to Adobe's Understanding AEM Sites offerings article. Each path carries a different cost shape. The 6.5 paths carry a license and a support contract tied to your version, while Cloud Service bundles the platform into a recurring subscription. Pull the subscription or license terms, the support tier, the metered units (if any), and any specialist partner rates from your own contract, and confirm which items renew automatically and on what notice period.

Drupal removes the software line entirely. Drupal core and the contributed projects on Drupal.org are licensed under GPL-2.0-or-later, and there is no paid edition of Drupal itself, so the budget that would have gone to a license moves to hosting, build, and support. The GPL does not require you to share code that is only used to run a website, so custom modules and themes written for your own sites can stay private. That point matters for regulated teams that want to keep integrations and workflow logic inside their own estate. Confirm with your legal team how your contributed and custom code will be stored and whether any third-party modules you rely on carry licenses other than GPL.

The license saving is real only if you replace the services Adobe was delivering. Those services include the support contract, the platform patching that AEM as a Cloud Service handles for you, and any Adobe-supplied extensions your authors use daily. On the Drupal side, you will fund hosting, a security patch process aligned with the Drupal core release schedule, and a partner or internal team for upgrades. Ask any implementation partner to quote these components separately from the build, so you can compare them line by line against your current AEM invoice.

The largest one-time cost in an AEM exit is usually the rebuild, not the software. Every AEM template, component and editorial workflow has to be mapped to something Drupal can express: content types and fields, paragraph or block patterns, and either a Drupal Canvas page layout or a theme built for the new front end. Ask your partner or internal team to inventory components by type and usage before quoting, because a few hundred templates used on every page cost far less to rebuild than a long tail of one-off pages. Multi-site structure, language variants and approval workflows also need explicit decisions, since Drupal's workflow and multilingual configuration will not copy AEM's launches or translation connectors one for one. DAM assets are the second large item. Moving binaries is simple; moving metadata, renditions, usage references and rights information is not. Confirm which asset metadata drives your sites, which renditions front ends depend on, and whether usage rights must be recorded in the new system. Assets and content are exported separately from AEM, and the sibling export guide covers that route, so this page does not repeat its steps. Your rebuild estimate should price the mapping and QA of each content type against the number of templates, not the raw asset count. Legacy sources change the math. Drupal 6 and 7 sites cannot be updated in place to Drupal 10 or later, so they are migrated into a new site with the core Migrate modules or Drush, and themes must be rebuilt. If your source is an older Drupal estate rather than AEM, include that theme rebuild in the one-time cost. For AEM sources, the payback period depends on how much of the rebuild you can complete before core support for AEM 6.5 ends on February 28, 2027, so confirm the schedule with your AEM contract owner early.

The cost decision is bounded by two dates. Core support for on-premise AEM 6.5 runs until February 28, 2027, and extended support, which covers critical fixes only, runs until February 28, 2028, according to Adobe's AEM 6.5 on-premise support timelines. After core support ends, the license you are paying for still buys you something, but the feature and non-critical fix cadence you rely on stops. Model every option against those dates, not against your next renewal invoice, because the contract you sign at renewal often determines what the migration costs in the months before the deadline.

Each path moves the cost timeline differently. A move to Drudal would put migration work, rebuilt themes, DAM replacement and hosting in your project plan, with most of the spend concentrated in the build window and recurring costs shifting to infrastructure, maintenance and support. Staying on AEM 6.5 LTS keeps the current license and skills in play but extends the same dependency and still ends its support path. AEM as a Cloud Service replaces the on-premise license with a subscription and a re-platforming effort, so the recurring line item stays with Adobe while the one-time effort is different. Ask Adobe and any partner to put each path into a written quote with dated milestones, and confirm which features and integrations each path would retain or lose.

Start the model now because the parts that take longest to price are the ones you cannot assess in a renewal negotiation: content and asset inventory, custom component counts, integrations with marketing and identity systems, and the editorial workflows that must be rebuilt. Inventory the AEM estate, export a representative sample of content and assets to test the export path, and record which teams depend on page authoring versus headless delivery. Those findings turn a renewal into a dated decision with a known exit cost. Teams that wait until renewal usually negotiate with less time to compare options and with less room to test a migration before core support ends.
