Why it can work

  • Office LTSC support is ending, so fleets must move versions.
  • Activation and licensing are hard for on-prem and air-gapped machines.
  • Removing old click-to-run installs fails silently or resists silent switches.

Watch out

  • Newer Office versions may need newer server operating systems.
  • Vendor support and EOL dates may shift the plan.

The job to be done

Migrate on-prem Office 2021 LTSC fleets before support ends

When Office 2021 LTSC support is ending and a fleet of on-prem desktops and servers must move to a supported version, the sysadmin needs a reliable way to upgrade, remove, and license Office across the fleet, so they can stay supported without breaking users or air-gapped machines.

Upgrading Office 2021 LTSC to 2024 LTSC via deployment, a popup on the test machine demands uninstalling Office 2021 and Visio first, blocking the in-place upgrade.
r/sysadmin6 upvotes
Removing Office 2021 LTSC in air-gapped machines with a remove config failed silently until the latest ODT was used
r/sysadmin4 upvotes
One GPO sets update path for Office 2021 LTSC and 2024 LTSC on 100 PCs and cannot separate the two during upgrade

Office 2024 LTSC does not include Publisher, so Publisher 2021 or 2019 must be kept, but the ODT will not install 2021 alongside 2024 or the reverse.
r/sysadmin3 upvotes
Old Office 2019/2021 C2R installs cannot be removed with ODT, and MDM uninstalls fail when apps are open with no silent/force switches found
r/sysadmin2 upvotes
Chose Office LTSC 2024 over 2021 because 2021 ends support Oct 13 2026; activation via OSPP.VBS problematic and license is expensive
r/sysadmin1 upvotes
Confusion that Office 2021 end of support in October 2026 leaves Windows Server 2019 without a supported Office version, while the server OS is supported until October…
r/sysadmin1 upvotes
Server 2019 needs an Office version past October EOL; Office 2021 only buys one year and Office 2024 requires Server 2022
