Dynamics CRM 2016 reached end of support on January 13, 2026, and on-premises Dynamics 365 Customer Engagement 9.x leaves mainstream support on January 12, 2027. How to choose the next CRM, and why the plugins, integrations and reports built around the old one decide the timeline.

Plugins and custom workflows written against the old SDK.
Integrations: the ERP sync, the website forms, the email marketing tool, the phone system.
Reports, often built in SSRS directly against the CRM database, which no SaaS CRM allows.
Data quality. Duplicates and dead records migrate perfectly and cost money per seat and per record forever after.
Inventory customizations and integrations, and mark each keep, replace with a product feature, or drop.
Clean and deduplicate before migrating, not after.
Move reporting to a separate data store fed from the CRM, so reports survive the change and any future one.
Migrate in one cutover for the core sales team; keep the old system read-only for a defined period.
Once a month: what changed in tech that month and what it means for you, from cloud and AI to security and the tools you build with. Every item links to its source. No sales pitch, unsubscribe in one click.
