# Change the Schedule for Existing Series

**Use this when:** you've changed a feed's cadence, run time, timezone, weekdays or end condition, and the schedules **already running** should adopt it too.

By default they won't — and that's deliberate. A feed save must never silently rewrite live schedules.

---

## The Two Routes

Both end at the same preview-and-confirm screen.

### Route A — while saving the feed

1. Edit the feed at **Forms → (your form) → Settings → Recurring Submissions**.
2. Before saving, tick **"Apply the updated schedule to N existing series."** It is unchecked every time.
3. Save. Queue opens a preview. **Nothing has propagated yet.**
4. Review and confirm.

### Route B — after saving

1. Save your feed changes normally.
2. Follow **"Preview and apply saved schedule to existing series."**
3. Review and confirm.

## Choosing Which Series

On the preview screen:

- **Enter specific series IDs** to target a subset, or
- **leave the selection blank** to target every non-completed series on that feed.

---

## What the Preview Shows

| Item | Why it matters |
| --- | --- |
| **Affected count** | How many series this will touch. |
| **Representative current schedule** | What they look like now. |
| **Representative proposed schedule** | What they'll look like after. |
| **Proposed targets** | The actual next dates they'll move to. |

Read the proposed targets carefully — they are the part people are surprised by.

---

## What Application Does

| Copies | Preserves | Never does |
| --- | --- | --- |
| Schedule settings | Progress and successful counts | Backfills missed occurrences |
| A new series revision | Attempt history | Resumes a paused series |
| A recalculated **future** target | Input mode and other execution choices | Touches locked or concurrently changed series |

Locked or concurrently changed series are **skipped and reported** — you'll see which ones didn't apply.

Work runs in bounded batches, so a feed with hundreds of series completes without timing out.

---

## What Is *Not* Applied

Application deliberately covers **schedule** settings only. These stay as each series recorded them:

- Input mode (Snapshot / Dynamic).
- Other execution choices.

A schedule snapshot is not a freeze of every feed setting: feed activation and live submission-related settings keep their runtime behaviour regardless.

---

## Choosing the Right Tool

| Goal | Tool |
| --- | --- |
| Change how often *new* series repeat | Edit the feed. Done. |
| Change how often *existing* series repeat | Edit the feed, then apply the saved schedule. |
| Move **one** series to a different date | **Change next submission** on that series. |
| Move **one** series to a different cadence | Edit the feed, then apply the saved schedule to that series ID only. |
| Stop a feed's schedules temporarily | Deactivate the feed. |

## Worked Example

A weekly Monday 09:00 check-in should become fortnightly on Wednesdays at 14:00, for the 40 series already running.

1. Edit the feed: **Repeat every** `2`, **Calendar unit** `Weeks`, **Specified time** `14:00`, uncheck every weekday except Wednesday.
2. Preview the next five occurrences and confirm they read the way you expect.
3. Tick **"Apply the updated schedule to 40 existing series."**
4. Save, and read the preview: 40 affected, current *weekly Monday 09:00*, proposed *fortnightly Wednesday 14:00*, with the proposed next dates listed.
5. Confirm.

All 40 keep their progress, their limits and their history. None of them backfill. Any that were mid-submission are skipped and listed, so you can re-apply to those afterwards.
