Migrate tracking journeys as consent-aware state machines, preserving session identity, offline queues, background policy, and event ordering across SDK lines.
The repository names establish a strong lineage candidate; package coordinates, supported Android matrix, background behavior, and entitlement must still be confirmed for the target release.
Legacy sources are fully covered. Candidate links expose the closest public evidence and its maturity; they do not silently upgrade it to an entitlement or support declaration.
mapmyindia-intouch-android-sdkmappls-intouch-android-sdkResolve each dimension explicitly. “It compiled” does not prove identity, lifecycle, failure, privacy, or operational compatibility.
Device, user, session, and vehicle identifiers can be implicit in SDK setup.
Map each durable identifier and ownership rule explicitly before moving history or live sessions.
Identity mapping plus start/restart/logout/reinstall tests with no duplicate active session.
Older Android behavior may rely on obsolete service or permission assumptions.
Implement the current permission, foreground-service, notification, battery, and background policy.
Physical-device matrix across denial, process death, reboot, power saver, offline, and upgrade.
Callbacks and local queues can differ in order and retry behavior.
Persist event identity, observed time, attempt, and reconciliation state above the SDK.
Gap, duplicate, late, and out-of-order event injection with recovery evidence.
Do not advance on calendar alone. Each stage creates evidence that makes the next one safe and reversible.
Inventory every tracking SDK integration, package, host, credential class, callback, and owner before changing production.
Resolve the exact entitled package or endpoint with Mappls and verify its supported toolchain, region, quotas, authentication, and lifecycle.
Move tracking SDK integration calls behind a narrow application-owned interface without changing product behavior.
Replay approved fixtures and shadow eligible reads while preventing duplicate writes or user-visible duplicate sessions or events.
Release to internal users and bounded cohorts with health gates, ownership, automatic stop conditions, and immutable version evidence.
Remove legacy credentials and dependencies only after rollback and audit retention obligations expire.
These examples deliberately model the seam and verification pattern—not unconfirmed package symbols. Implement the adapters only after the exact target contract is issued.

// Run this journey against a deterministic fake and each entitled SDK adapter.The candidate and exact package/endpoint versions are approved by the owning Mappls product team for the target account and region.
Journey-level contract tests pass on every supported device, browser, architecture, and release build—not only a debug simulator.
Security, privacy, accessibility, performance, quota, observability, and support owners accept measured differences.
A bounded cohort completes the agreed observation window without an unresolved severity-one or severity-two regression.
Stopping traffic is not enough. Recover durable resources, sessions, events, and in-flight commands without duplicates or hidden divergence.
Prepare support packetKeep the previous signed artifact, dependency lock, configuration, and credential valid until the observation window closes.
Make the provider selection server- or release-controlled; define automatic stop signals and one accountable rollback owner.
For durable state, prove backward-readable records or a reversible data migration before allowing candidate writes.
After rollback, reconcile in-flight requests and resources by stable identifiers instead of replaying commands blindly.
