Free Cutover Plan Template (Excel)
What's in the Cutover Plan template
The Cutover Plan sheet holds one row per task, up to 60, with task name, start time (decimal hour, e.g. 22.5 for 10:30 PM), duration, responsible person, status, a critical-path Yes/No flag, and a rollback note.
End time calculates automatically from start time plus duration, so you can see your whole cutover-night timeline update as you adjust any task's duration.
The summary below the table shows overall % complete, how many tasks are on the critical path, how many of those are done, how many tasks are blocked, and total duration for all tasks versus just the critical path.
Why decimal hours instead of a time-of-day format
Cutover timelines are usually built around a maintenance window that runs past midnight - Excel's time-of-day formatting makes that awkward to add and subtract without extra logic.
Decimal hours (22.5 = 10:30 PM, 25.5 = 1:30 AM the next day) add and subtract with plain arithmetic, so end time = start time + duration always works, even across the midnight boundary.
This template calculates the day-of timeline and completion status - it doesn't produce a rollback runbook document or stakeholder sign-off log; the Rollback note column is a short flag, not a full rollback procedure.
Who this template is for
IT and ops teams running a system, application, or ERP cutover with a defined maintenance window and a checklist of sequenced tasks that need go/no-go tracking on the night.
It's built for a single owner tracking the cutover checklist live during the window, not for a multi-team real-time collaboration tool.
How to use it
- List every cutover task on the Cutover Plan sheet with start time (decimal hour), duration, responsible person and critical-path flag.
- Update status to Done as each task finishes - end time and % complete calculate automatically.
- Check the summary below the table for % complete, critical-path task count and hours, and blocked tasks.

Frequently asked questions
Why decimal hours instead of a clock time format?
Decimal hours (22.5 = 10:30 PM) add and subtract with plain arithmetic, including across midnight, without the formatting quirks of Excel's built-in time-of-day values.
Does this include a full rollback runbook?
No. The Rollback note column is a short flag per task, not a complete rollback procedure document - use it alongside your existing rollback documentation.
How is % complete calculated?
Tasks marked Done divided by all tasks logged (tasks with a duration entered). It updates automatically as you change task status.
Can I use this in Google Sheets?
Yes. Upload the downloaded file to Google Drive, then open it and choose File > Save as Google Sheets. All formulas keep working.
How many tasks can I plan?
Up to 60 rows - enough for most single-system or single-application cutover windows.
What's the usage license?
Personal use or use within one business. It's not meant to be resold or redistributed as a template product.
