# Test a Confluence migration with a dry run

To test a Confluence migration without changing anything, open the Migration tab in your Capable app, filter to one space, choose the app and macros, and press **Perform verification**. It reads every matching page and writes nothing. Read the failures, then pilot a real run on that one space before going wider.

## Before you start

* You need to be a Confluence site administrator.
* Keep the app you are moving away from installed. The migration reads its content.
* Pick a space you know well, so you can judge the results.

## Steps

1. Open Confluence settings, find your Capable app and open the **Migration** tab.
2. On **Introduction**, read the acknowledgements and tick them.
3. On **Options**, leave the defaults unless you are moving off a standalone Capable app.
4. On **Select apps**, type a filter for one space, such as `space = ENG`, then tick the app you are moving away from.
5. On **Select macros**, tick the macros you want and read each expander.
6. Press **Perform verification**.
7. Read the results. **Macros failed** is the number that matters.

## What happens next

If failures look explainable, run the same selection for real with **Start migration**, then press **Download log** before you go anywhere else. Verification uses a stand-in drawing for draw.io, so a clean dry run does not prove diagrams will migrate: the pilot run does. If every count is zero, your space filter was probably rejected; write it as `space = "KEY"` or `space in ("A","B")`.
