Per Adobe's published release roadmap:

• Adobe Managed Services (AMS) customers: AEM 6.5 support ends August 31, 2026.
  ‍
• On-premise customers: core support for AEM 6.5 ends February 28, 2027, with each 6.5 service pack supported up to 18 months from release.
  ‍
• Extended support for AEM 6.5 ends February 28, 2028, per Adobe's Products and Technical Support Periods matrix. Extended support is a paid program intended as migration runway, not a long-term operating plan.
  ‍
• AEM 6.5 LTS extends the on-premise path with support for Java 17 and 21, though some legacy features and artifacts have been removed and require impact analysis.

Your site will not stop working when support ends. What stops is everything that keeps an enterprise platform safe to operate: security patches, product support, and compatibility updates. For organizations in regulated industries, running an unsupported CMS is a compliance finding waiting to be written.

The Decision

Upgrade, migrate, or wait?

Wait. The lowest effort option and the highest risk. Unpatched vulnerabilities accumulate, integrations drift out of compatibility, and the eventual migration gets harder every quarter as the gap between your codebase and current AEM patterns widens. Waiting is a decision to migrate later, under pressure, at a higher cost.

‍Upgrade to 6.5 LTS. A legitimate path for organizations with hard requirements to stay on-premise: data residency mandates, air-gapped environments, or deep infrastructure dependencies that cannot move yet. LTS buys time and modern Java support. It does not change the fundamental model. You still own infrastructure, upgrades, scaling, and patching, and you will face another version decision down the road.

Migrate to AEM as a Cloud Service. Adobe's primary investment path. The evergreen model means continuous updates instead of version upgrades, so this is the last EOL migration you will plan. Auto-scaling replaces capacity planning. Security patching becomes Adobe's job. New Adobe capabilities, including its AI features, ship to Cloud Service first.

For most organizations without a hard on-premise constraint, Cloud Service is the destination. The real question is not whether but how, and how well.

The Challenge

A cloud migration is not a lift and shift

AEM as a Cloud Service is a different architecture, not a hosted copy of 6.5. A realistic plan accounts for:

• Code refactoring. Immutable content repositories, containerized runtimes, and Cloud Service API patterns mean custom code, workflows, and OSGi configurations need review and often rework. Adobe's Best Practices Analyzer and Cloud Acceleration tooling identify the gaps; engineering closes them.
• Dispatcher and CDN changes. Caching and delivery move to a managed CDN model with validated dispatcher configurations.
• Asset and content migration. Large DAM libraries, versions, and metadata need a migration strategy that preserves fidelity without freezing authoring for weeks.
• Integration re-validation. CRM, commerce, analytics, search, and marketing automation connections built against 6.5 endpoints need testing against Cloud Service equivalents.
• CI/CD adoption. Cloud Manager pipelines with enforced quality gates replace whatever deployment process you run today. This is an opportunity, not just a requirement.

This is exactly the kind of work where disciplined engineering pays for itself. It is also where a rushed migration produces the outages and regressions that give cloud projects a bad name.

Our Approach

Assess first. Migrate with evidence.

We run migrations the way we run every engagement: discovery before design, proof before commitment, and quality gates before deployment.

• Migration Readiness Assessment. We review your current AEM implementation: custom code, templates and components, integrations, content and asset volumes, and operational dependencies. You receive a findings report with a complexity rating, a remediation inventory, and a realistic effort estimate. This is useful whether or not you engage us for the migration itself.
• Solution blueprint. Target architecture on Cloud Service, integration mapping, content migration strategy, and a phased plan sized into manageable milestones rather than a big-bang cutover.
• Build and refactor. Sprint cycles with functional and integration test execution, performance tuning, and stakeholder demos at every phase.
• Migrate, validate, deploy. Content and asset migration with fidelity checks, UAT, go-live, and post-launch monitoring and tuning.
• Train and support. Your authors and engineers take over a platform they understand, with documentation written for the people who will extend it.

This is exactly the kind of work where disciplined engineering pays for itself. It is also where a rushed migration produces the outages and regressions that give cloud projects a bad name.

Why PiSrc?

AEM Depth. Modern AI ready.

• Adobe Partners with certified AEM architects and developers across Experience Manager, Target, Analytics, Campaign, and Assets. We have worked with S&P 500 organizations in media, retail, financial services, healthcare, and manufacturing since 2018.
• Quality engineering as a discipline. Resilient, fast, maintainable code, reviewed and documented so your team can sustain it after the engagement. We size projects into achievable phases and avoid vast transformation programs that stall.
• An AI-ready foundation, not just a version change. Migration is the natural moment to modernize what your platform can do. PiSrc builds AI products for AEM: Metaphora converts legacy PDFs into authorable pages and translates content at scale with brand voice intact, and Prism turns site search and chat into cited, knowledge-grounded conversations that qualify leads. Migrate with PiSrc and the roadmap conversation includes what AEM can do next, not just where it runs.
• Content and asset migration with fidelity checks, UAT, go-live, and post-launch monitoring and tuning.

FAQ

Assess first. Migrate with evidence.

We run migrations the way we run every engagement: discovery before design, proof before commitment, and quality gates before deployment.

• We are on Adobe Managed Services. Does the February 2027 date apply to us? No. Per Adobe's roadmap, AMS support for AEM 6.5 ends August 31, 2026, earlier than the on-premise core support date. If you are on AMS and have not started planning, this is urgent.
• Is 6.5 LTS a bad choice? No. It is the right choice for organizations with hard on-premise constraints. It is the wrong choice as a way to avoid deciding. LTS requires its own upgrade effort, including Java 17/21 compatibility and review of removed legacy features, so treat it as a project, not a pause button.
• How long does a Cloud Service migration take? It depends on customization depth, integration count, and content volume, which is exactly what the readiness assessment quantifies. We size engagements into manageable phases and give you an evidence-based timeline rather than a generic one.
• Will our authors need retraining? The authoring experience on Cloud Service is familiar to 6.5 authors, with differences concentrated in areas like asset workflows and publishing. Training is included in our engagement structure.
• Can you also handle the content problems we have been deferring, like our PDF library? Yes. Metaphora converts PDF libraries into authorable, translatable, searchable AEM pages, and many clients fold this into the migration so the new platform launches with more usable content than the old one had.
