The framework for legally deploying and using Microsoft Exchange Server or Exchange Online, based on server and client access models.
Thank you for sharing.
As Microsoft transitions to the Subscription Edition (SE) model for Exchange Server, I understand your concerns about the relevance of renewing licenses for a product that is approaching end-of-support. From my knowledge and the research, I’ve gathered, here’s the relevant information and I hope they’ll be useful for you.
- Your existing Exchange Server 2019 CALs remain valid and fully supported for the remainder of your Open Value Agreement, provided they are covered by active Software Assurance (SA). Microsoft Open Programs | Microsoft Volume Licensing
- Microsoft allows customers with active SA to upgrade to Exchange Server Subscription Edition without requiring new CAL purchases. The CALs for Exchange 2019 are compatible with Exchange SE.
Microsoft’s official Upgrading to Exchange Server Subscription Edition (SE) | Microsoft Learn confirms:
This confirms that the upgrade is seamless and does not invalidate your existing CALs.Exchange Server SE supports an in-place upgrade from Exchange Server 2019 CU14 or CU15. This process allows you to install Exchange Server SE over your existing Exchange Server 2019 installation, similar to the procedure for applying cumulative updates.” Exchange Server SE RTM does not require a new product key. It will continue to function after a legacy or in-place upgrade.”
- You will continue to receive updates and support under your current agreement, and there is no additional licensing cost associated with transitioning to Exchange SE during the term of your agreement. In Microsoft Product Terms
This means if your Exchange 2019 CALs are covered by active SA, they are valid for use with Exchange SE. You do not need to purchase new CALs during the remaining term of your Open Value Agreement.“All CALs used to access the software under this model must also be acquired as subscription licenses or have active Software Assurance.”
Additionally, if your licenses were purchased through Ingram Micro, this does not negatively impact the validity of your Open Value Agreement or your ability to upgrade to Exchange SE. Ingram Micro is an authorized Microsoft distributor and provides licenses under official Microsoft programs such as Open Value, Open Value Subscription, and CSP.
There are no special restrictions or limitations imposed by Microsoft on licenses purchased via Ingram Micro in relation to the upgrade to Exchange SE.
