| Date | Milestone | Official source |
|---|---|---|
| January 15, 2030 | The Dynamics SL Service Plan ends. It is the last day to add perpetual users, and hosting under SPLA is expected to end. This Service Plan date does not extend Dynamics SL product security support. | [Explore migration options for Microsoft Dynamics GP and Microsoft Dynamics SL customers](https://www.microsoft.com/en-us/dynamics-365/blog/business-leader/2025/06/05/explore-migration-options-for-microsoft-dynamics-gp-and-microsoft-dynamics-sl-customers/) |

## What is Microsoft Dynamics SL?

Microsoft Dynamics SL, formerly Solomon, is an enterprise resource planning (ERP) product with finance and project accounting.

The Service Plan deadline is not an extension of product security support. Confirm licensing and migration prerequisites for your installed version.

## Successors and migration paths

**Successors and version-specific migration prerequisites. Source: MS Dynamics Guys End-of-Support Tracker (msdynamicsguys.com).**

| Product | Successor | Path boundary | Microsoft documentation |
|---|---|---|---|
| Dynamics SL | Microsoft Dynamics 365 Business Central | Microsoft's migration prerequisites allow Dynamics SL 2015 or later. The SL 2015 Lifecycle note instead requires an upgrade to SL 2018 before moving to Business Central. Confirm the starting version with Microsoft before planning the move. | [Cloud Migration Prerequisites for Dynamics SL](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/cloud-migration-prerequisites-sl); [Dynamics SL migration to Business Central online: process overview](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/migrate-sl-overview); [Dynamics SL 2015 - Microsoft Lifecycle](https://learn.microsoft.com/en-us/lifecycle/products/dynamics-sl-2015) |

The product path is not a project plan. See [Microsoft Dynamics 365 migration and upgrade planning](https://msdynamicsguys.com/migrations/) for scope, rehearsals and ownership.

## Questions about dynamics sl end of life

### When does Dynamics SL support end?

SL 2018 extended support ends on July 11, 2028. SL 2015 extended support ended on January 14, 2025. MS Dynamics Guys separates those product dates from the Service Plan.

### What is the Dynamics SL Service Plan deadline?

Microsoft gives January 15, 2030 for the Service Plan boundary and additional perpetual-user licensing. It describes the SPLA subscription end as expected. That is not a security-support extension.

### Is Solomon the same as Microsoft Dynamics SL?

Solomon is the former name of Microsoft Dynamics SL. SL is an enterprise resource planning product with finance and project accounting.

### Why do SL mainstream support dates differ?

The Microsoft product-page note gives January 9, 2024 after an extension. A later Microsoft blog repeats the old date. MS Dynamics Guys follows the product-page note.

### Can SL migrate to Business Central?

Microsoft provides tools for moving SL data to Microsoft Dynamics 365 Business Central online. Its Lifecycle note and migration prerequisites differ on the starting version. Confirm the required upgrade before scheduling a migration.

### Can I use these dates without entering my email?

Yes. The MS Dynamics Guys CSV, JSON and calendar downloads are ungated. Keep the source links and CC BY 4.0 credit when you reuse them.

## How MS Dynamics Guys checked these dates

MS Dynamics Guys checked the SL product records and Microsoft's licensing announcement on October 10, 2026. The SL 2018 product note controls its revised mainstream support date.

Reviewed by Paul Francis. The [tracker method](https://msdynamicsguys.com/lifecycle/#method) explains Pacific-day calculations and why a fresh countdown does not imply a fresh source review.
