Uso
The primary use case of merge history is to clean up after the situation in which someone moves a page by cut and paste (rather than going through the proper move page forms).
This tool allows for the licensing violation caused by the original cut and paste to be repaired, and the history to be reconnected, creating a situation almost indistinguishable from if the cut-paste had never happened.

Vaya a Special:MergeHistory. Ingrese los títulos de la página de origen y la página de destino en los campos de entrada provistos. La página de origen es la página cuya revisión desea fusionar en otra página, mientras que la página de destino es la página en la que se fusionará la revisión.
Haga clic en "Mostrar ediciones fusionables".
Se le mostrará una lista de revisiones de la página de origen que se puede combinar en la página de destino.
Initially, only the right column of radio buttons is visible, and the left column is hidden.
Simple merges
| This section en pocas palabras: For simple merges, select either zero or one radio button on the right-hand column next to a revision. Leave the left-hand column blank. All revisions that are older than the selected revision (or all revisions if none was selected) will be merged into the destination page. |

- For a simple merge, only edits that are older than the oldest version of the destination page can be moved.
- If you want to merge all of the edits to the source page, and they are all older than the oldest version of the destination page, then you can leave both sets of radio buttons blank. The source page will become a redirect to the destination page.
- Haga clic en el botón de radio junto a una revisión para seleccionarla. That revision, and any revisions older than it, will be moved to the destination page.
- Once you've selected the revisions you want, click on
Fusionar revisionesto perform the merge. - Si la fusión se realizó correctamente, debería ver una página similar a esta.

Clearing the way for a simple merge
- Si la página de destino comenzó como una redirección a la página de origen, provocará una superposición en las revisiones, evitando así una MergeHistory completa.
Para arreglar esto:
- Eliminar la página de destino.
- Restaurar todo menos las revisiones previamente eliminadas y redirigidas.
Ahora es posible que ocurra un MergeHistory.
Complex merges
| Versión de MediaWiki: | ≥ 1.45 |
| This section en pocas palabras: For complex merges, select two radio buttons, the older one on the left column and the newer one on the right column. Only those two revisions and the revisions between them will be merged. |
While the simple merge UI should be sufficient for cleaning up after a standard cut-paste move, in unusual circumstances you may want more control over which revisions to merge.
In that case, you can select a newest revision to merge in the right column of radio buttons, and an oldest revision to merge in the left column of radio buttons. Only those two revisions, and the revisions between them (if any) will be merged.
Complex merges are not subject to the limitation that all of the revisions merged are older than the oldest version of the destination page. However, they are subject to their own separate requirements.
- The merged revisions must fit as a clean block in the destination page history. That is, there must be no revisions of the destination page between the oldest merged revision and the newest merged revision.
- If you really want to entangle two pages like that, you can do it via multiple complex merges.
- You can't change the current revision of either page via a complex merge (hence, the newest revision of the source page can't be merged, nor can revisions of the source page newer than the newest revision of the destination page).
Complex merges are a powertool that can easily do unexpected and dangerous things, such as decontextualizing a diff and making it appear that an editor did something they did not do. Only do this if you are very sure you know what you are doing.
