| 5 | +# How to Update: MultiMC |
| 6 | + |
| 7 | +{% hint style="danger" %} |
| 8 | +**You should ALWAYS [make backups](../backup/multimc.md) before updating**. |
| 9 | + |
| 10 | +As with any other piece of software, updates may go wrong for many reasons, including but not limited to: the launcher, the hardware, your custom configuration, the mods you added... and, rarely, FO as well. |
| 11 | +{% endhint %} |
| 12 | + |
| 13 | +{% hint style="success" %} |
| 14 | +If you had installed [FO on MultiMC **with** automatic updates](../install/multimc.md#automatic-updates), and you're not updating to a newer version of Minecraft, you just need to open the existing versions. |
| 15 | + |
| 16 | +If you get a popup saying **This modpack uses new versions of the following...**, click on the **Update** button. |
| 17 | +{% endhint %} |
| 18 | + |
| 19 | +If you had installed [FO on MultiMC **without** automatic updates](../install/multimc.md#easier-installation), or if you're updating to a new version of Minecraft: |
| 20 | + |
| 21 | +1. Follow the [FO installation instructions for MultiMC](../install/multimc.md) again. This will create a new instance |
| 22 | +2. In **MultiMC**, click on the previous version |
| 23 | +3. Click on **Minecraft Folder** |
| 24 | +4. Click on the new version as well |
| 25 | +5. Click on **Minecraft Folder** |
| 26 | +6. Copy the following files from the folder you opened in _step 3_ to the folder you opened in _step 5_: |
| 27 | + * `saves`: Your local worlds |
| 28 | + * `resourcepacks`: Your resource packs, if any. If you're asked to replace files, do not! |
| 29 | + * `shaders`: Your shaders, if any |
| 30 | + * `screenshots`: Your screenshots, if any |
| 31 | + * `server.dat`: Your multiplayer servers, if any |
| 32 | + * `options.txt`: Your custom options and keybinds, if any. If you want the [recommended FO settings](../info/options.md), do not copy it |
| 33 | +7. Once you've moved them, launch the new instance. Minecraft should open up |
| 34 | +8. If you can see the newly installed version in the bottom-right corner, you can delete the previous version from _step 2_ |
