Dynamics GP is moving to a Modern Lifecycle Policy, which means that the product is serviced and supported continuously, as long as you maintain your license and keep current with the service terms and system requirements.
Your VAR partner will keep you updated with that – you won’t even have to think about it. This is a positive move because it shows that Microsoft is committed to Dynamics GP for the foreseeable future.
Upgrades and updates will be released more frequently and on a predictable schedule throughout each year. Changes like non-security and security updates, new product builds, new feature requests, access to online content including Knowledge Base and webcasts, phone support, and online support will all be continuously updated for you.
Microsoft will give you ample time of notice before any action is required on your part.
