In one of our migrations, old resources stayed in a legacy metadata store while new resources went to the target until a reconciliation workflow caught up.

Migration observability needs a different category:\u00a0Semantic drift.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Drift is the distance between what the legacy system means and what the target system currently means for the same logical resource or workflow decision. Ordinary service monitoring usually misses it. Requests still return 200. Workflows\u00a0complete. Consumers get answers. The answers may no longer mean the same thing.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">In a live control-plane migration, drift shows up in several forms:\u00a0A\u00a0resource exists in one store but not the other; the same resource is in both stores but one copy is newer; both copies have the same timestamp but different content; the target can answer a read but not with the semantics the legacy path used; shared infrastructure cleanup decisions differ depending on which store is consulted; a downstream component falls back to the legacy path more often than expected because parity hasn\u2019t converged.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">These are the signals that tell you whether the migration is still controlled or has started drifting.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">We started treating drift as a first-class metric after a cleanup workflow made the wrong decision based on an incomplete view of active resources. Before that, we tracked progress. After, we tracked the meaning. I\u2019m still not sure we have the right drift metrics for every scenario. It\u2019s an evolving practice. But the shift in mindset was worth it on its own.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<h3><span data-contrast=\"none\">Drift\u00a0Budgets Make Cutover Decisions Defensible<\/span><span data-ccp-props='{\"134245418\":true,\"134245529\":true,\"335559738\":160,\"335559739\":80}'>\u00a0<\/span><\/h3>\n<p><span data-contrast=\"auto\">In SRE, error budgets\u00a0turn\u00a0a subjective question\u00a0(Does this feel stable enough?)\u00a0into an operational contract.

A drift budget says how much semantic divergence the platform is willing to tolerate at each phase.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Early in a migration, the budget may allow some controlled mismatch. Dual reads are still enabled. The reconciliation workflow is expected to copy records for a while. Fallback reads may be normal. Later, tolerated\u00a0drift\u00a0should shrink. By the time the target control\u00a0plane is primary for\u00a0provisioning\u00a0and rollback risk is being reduced, the budget should be tight enough that unresolved differences are blockers, not background noise.<\/span><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">This changes how cutover conversations go.

A healthy migration shows fallback trending down as reconciliation catches up. If fallback stays flat or spikes after switch-over, the migration has moved traffic faster than it has moved meaning. We saw exactly that pattern once. Fallback plateaued at about 15% for a specific resource class. The target lookup path was returning a subtly different answer for resources with compartment-level dependencies. The dual-read metric told us. The rest of our monitoring\u00a0didn\u2019t.
