Sitecore is retiring support for LTSC2019-based container images in the Public ACR to ensure customers are running on supported and secure Windows container platforms. The affected images are: xmcloud/sitecore-xmcloud-cm, xmcloud/sitecore-xmcloud-mssql-init, and xmcloud/sitecore-xmcloud-solr-init.
Key Dates
Final LTSC2019 image release: 15 Sep 2026
LTSC2019 images retained in Public ACR until: 31 Mar 2027
Recommendation: Customers currently using LTSC2019 images should migrate to LTSC2022 or LTSC2025, both of which continue to receive security updates, bug fixes, and monthly releases.
After 15 Sep 2026, LTSC2019 images will no longer receive updates or maintenance.
