Migradock: Migration Lab
Sequence Safer DB Changes
$2.99 · Designed for iPad. Not verified for macOS.
Put a zero-downtime database migration on one screen: a dependency-aware runway from the first expand step to the final contract, on a phase-colored timeline.
Migradock puts a zero-downtime database migration plan on one screen: a dependency-aware runway from the first expand step to the final contract.
The app opens directly into a phase-colored timeline chart that schedules every step after its dependencies and plots start and end in elapsed minutes across the five classic phases — Expand, Backfill, Switch, Validate, Contract. Three badges summarize the plan at a glance: an overall risk score, the critical-path duration, and the longest table lock. The Sequence evidence list shows each step with its predecessors and whether it has been rehearsed, and the Release gate section renders a decision — Ready for review, Conditional approval, or Blocked until irreversible steps are rehearsed — alongside an adjustable lock budget slider and a reminder to keep expand and contract deployments separate.

Version 1.1 is a focused redesign: Migradock now opens directly into a single, fast migration runway. The timeline chart schedules every step from its dependencies across the expand-to-contract phases, badges surface risk, critical path, and max lock at a glance, and the release gate shows a clear go/no-go decision with an adjustable lock budget.
