A spreadsheet migration goes wrong when a team copies messy scheduling habits into a new system. The goal is not to recreate every tab. The goal is to move live scheduling work into clearer records, rules, ownership, and review workflows.
Use this checklist alongside the full Google Sheets migration guide. It is designed for managers who want a practical cutover path without building a heavy implementation project.
Pre-migration inventory
List every active schedule sheet, availability form, coverage tracker, swap log, screenshot workflow, and side document. Identify which items are live sources of truth and which are archives.
Mark duplicate tabs and old copies so the team knows what should not be imported.
Worker records
Create a clean list of active workers, returning workers, inactive workers, and invited or pending workers. Remove duplicate names and unclear status labels.
Add manager-owned notes only where they help scheduling decisions.
Shift types
Define the shift types managers actually schedule: front desk, event, lead, closing, coverage-only, training, or other team-specific patterns.
Clean shift types make eligibility and reporting easier later.
Locations/posts
List locations, desks, posts, departments, buildings, or event areas. Remove old labels that no longer guide scheduling decisions.
Managers should know which shifts require location-specific training or access.
Availability fields
Standardize available windows, unavailable windows, preferred shifts, effective dates, semester or schedule period, and max desired hours where relevant.
Avoid migrating free-text availability without turning it into reviewable fields.
Eligibility rules
Document who can work which roles, locations, departments, or lead responsibilities. If eligibility lives in one manager’s memory, capture it before launch.
Eligibility rules should be checked before assignments and coverage acceptance.
Coverage/swap rules
Define how workers request coverage, who can accept, when manager approval is required, and when ownership transfers.
This prevents the new system from becoming a calendar while group chats remain the real coverage workflow.
Approval workflows
Decide which changes require manager approval, which can be reviewed quickly, and which should create warnings. Keep the workflow practical enough that managers will actually use it.
Approval state should be visible before the final schedule changes.
Parallel testing
Run a short test period where managers compare the structured schedule against the old sheet. Look for missing workers, unclear locations, eligibility mistakes, and notification gaps.
Name one owner for deciding which system is authoritative during the test.
Cutover plan
Choose the schedule period when the new workflow becomes official. Tell workers where to view shifts, request coverage, and check final updates.
A cutover plan should include manager responsibilities and worker communication, not only data import.
Old spreadsheet retirement
Archive the old spreadsheet workflow after launch. Keep it for reference if useful, but do not let it remain a second live schedule.
If old sheets stay editable, version confusion can return immediately.
