Entra Connect Sync v2.1.15.0 was the first v2.x to be announced with Automatic Upgrades functionality, on July 6th 2022. However, Microsoft's support life cycle for Windows Server Operating Systems and .NET Framework versions would sometimes stand in the way of these upgrades. Entra Connect Sync v2.3.6.0 now comes with improvements in this area.

What’s New

Entra Connect Sync v2.3.6.0 offers a bug fix.

Improved Automatic Upgrade eligibility detection

Starting with Entra Connect Sync v2.3.6.0, Entra Connect Sync's Automatic Upgrade functionality will no longer retry if it detects the host does not meet the Operating System (OS) or .NET Framework requirements.

While this improvement limits automatic upgrades to unsupported configurations, it results in Entra Connect Sync installations on outdated and possibly vulnerable versions. I bet that not every Identity admin experiences this as an improvement…
