Every managed endpoint should have a known owner and a current policy state. It should also run a supported operating system and have a defined update path. Teams should be able to measure how many devices meet that standard. Microsoft Configuration Manager 2503 reaches end of support on September 30, 2026, while version 2603 remains supported until November 5, 2027. The current task is to control the transition without creating policy or support blind spots.
Starting with Intune settings or a migration tool can miss that target. Endpoint work crosses inventory, identity, security policy, patching, enrollment, and user support. A useful plan works backward from the control level the business needs. It then tests whether the current platform and migration sequence can produce it.
Define the endpoint outcome before choosing the platform
A good endpoint program starts with measurable control. Each corporate device should be enrolled and visible. It should receive the right policy and report its health on time. Exceptions should have an owner and a due date. Those measures create a baseline for deciding whether the current model works.
Calance positions its Unified Endpoint Management Services around mixed device environments. These can include Windows, macOS, mobile devices, and thin clients. The service covers provisioning, Intune operations, patch governance, configuration baselines, and reporting. That scope matters because endpoint results depend on connected controls rather than one console.
Measure the exposure that the current model leaves behind
Measure the gap between the target state and the current fleet before planning a migration. Count unmanaged devices, unsupported operating systems, failed policy assignments, stale records, and machines that miss update targets. Then separate temporary exceptions from repeat failures.
Verizon's 2026 Data Breach Investigations Report found that vulnerability exploitation accounted for 31% of breaches. It also found that 35% of known exploited vulnerability instances were still open at day 28 in its 2025 dataset. Endpoint policy can't remove every exposure, but patch coverage and device visibility show where risk remains.
Decide what must stay in Configuration Manager during transition
A migration plan should begin with workload evidence. Some organizations still depend on Configuration Manager for app deployment and device collections. Others use it for imaging, reporting, or controls tied to local infrastructure. Moving those functions without mapping dependencies can break working processes.
Microsoft states that each Configuration Manager current branch release receives 18 months of support. Its current lifecycle schedule shows version 2503 ending support on September 30, 2026, version 2509 on May 12, 2027, and version 2603 on November 5, 2027. Those dates create planning points, but they don't mean every workload should move together.
A controlled SCCM to Intune Migration can use co-management while workloads move in stages. Calance treats Configuration Manager as the existing on-premises base and co-management as the transition state. Intune becomes the cloud target as workloads become ready. The useful milestone is workload readiness, not the date a tool gets installed.
Set identity and compliance conditions before moving policy
Cloud management depends on identity and device trust. A console entry isn't enough. The business must know who owns the device and which access rules apply. Those conditions need agreement before large policy moves begin.
NIST's Zero Trust Architecture guidance states that trust shouldn't come from network location or device ownership alone. It treats user and device authentication as separate checks before access to a resource. That gives endpoint teams a clear test. Policy, identity, and access decisions need to use the same device state.
Calance's Microsoft Intune Endpoint Management approach connects Intune with the wider Microsoft stack. That can include Entra ID, Conditional Access, Defender, Autopilot, and update controls. The mix can vary. The device state must feed an access decision. IT also needs to explain and test that decision.
Use leading indicators to test the migration sequence
Migration progress should be judged before final cutover. Useful indicators include enrollment success, policy assignment success, and patch compliance. Application delivery failures and help-desk volume can show where the change causes trouble. Teams should compare those measures by device group instead of trusting a fleet-wide average.
CISA's Cybersecurity Performance Goals support this outcome-based method. The goals help organizations set measurable security practices and assess progress against defined results. A migration stage should advance when evidence shows that controls are holding.
Build milestones around evidence instead of activity
A project milestone should prove a control result. "Pilot complete" says little by itself. A stronger milestone proves the pilot group enrolled and received required policies. It should also show that required apps installed and support stayed within the agreed threshold.
If one measure fails, the next group should wait while the team finds the cause. A failed policy may point to a device filter, identity group, legacy dependency, or enrollment path. The plan should change where the evidence fails.
Connect endpoint management to the wider cloud operating model
Endpoint controls depend on services outside the device platform. Identity, access, cloud resources, and user files can affect enrollment and device state. Teams should map those dependencies before they retire local controls.
Calance's Microsoft Azure cloud-native services work covers Entra ID and related Microsoft cloud services. For an endpoint program, the planning point is ownership. Each dependency needs an owner. That owner must approve changes and respond when endpoint evidence conflicts with identity or access results.
Use the review cycle to change weak assumptions
The endpoint plan should be reviewed when measurements diverge from the target. If enrollment is high but compliance remains low, the problem may be policy design or device health. If compliance is high but support tickets rise, the technical control may still work. The user process may be failing.
The first backward-planning question should stay visible throughout the work. What measurable device state must be true before the organization can call endpoint control successful? Every platform choice, migration stage, and exception rule should trace back to that answer.
Frequently asked questions
What should Unified Endpoint Management Services measure?
They should measure whether devices are known, enrolled, supported, and receiving required controls. Teams also need to track failed assignments and exceptions. The measures should show fleet coverage and the devices outside the target state.
Does moving to Intune require an immediate SCCM shutdown?
No. Configuration Manager remains supported under Microsoft's current lifecycle, and Calance describes co-management as a transition option. The right pace depends on workload dependencies and test results. Teams should move a workload when its replacement control has been proved.
What is the main risk in an SCCM to Intune migration?
The main risk is moving a control before its dependencies are understood. Application delivery, identity groups, device filters, or local infrastructure can affect the result. A pilot should test those links before the same change reaches a larger device group.
Which endpoint measures should appear first on a project dashboard?
Start with measures that show control coverage and failures. Enrollment status, compliance state, patch status, and policy errors can reveal whether the new model works. Add support measures when they help explain why a technical target is being missed.
How often should endpoint policy be reviewed?
Review policy when operating-system support changes, device groups change, or measurements show repeat exceptions. A scheduled review is useful, but event-based review matters too. The team should change a policy when evidence shows a weak result. The rule must still produce the intended device state.
What question should endpoint teams answer before selecting a tactic?
They should define the device state that will count as successful control. That answer should include the evidence used to prove it and the exceptions the business will accept. The first backward-planning question is this: what measurable endpoint state must be true? Answer that before choosing the tool or migration step.
