To extend https://forum.itflow.org/d/1569-feature-request-assets-tag-for-equipment-supported-eol-leased to software licensing, I would request the following two date fields added to the license template and to the licensing export report.
Mainstream Support
End of Life
Example:
Template Name: Windows Server 2016
Version: 2016
Description: Server Operating System
Type: Operating System
License Type: Device
Mainstream Support until: 01/11/2022
End of Life: 01/12/2027
With the ability to push template updates to linked licenses, it should help the licensing reports AND bring consistency to chaos. https://forum.itflow.org/d/1783-feature-request-tie-existing-licenses-back-to-license-template
Adding it to the licensing report, you are sitting down with a client and they have 20 Windows 10 machines still on the network, and until "End of Life: 10/14/2025" to get them replaced.
