# Upgrading Guide

To ensure a clean install when upgrading to a major or minor version (major.minor.patch), it is recommended to first make a backup and then remove the previous version of Timeflow and samples by following these steps:

1. In the Project view delete: \
   **Assets/Samples/Timeflow Animation System Samples**
2. In the Package Manager, locate and uninstall **Timeflow Animation System**
3. Then download and import the latest version.
4. Import samples from the packages **In Project**, listed under **Timeflow Animation System Samples**

The Timeflow preferences and settings are preserved, unless you also delete the assets in: **Assets/Plugins/Timeflow**

{% hint style="warning" %}
The above steps when followed in order prevent the occurrence of errors, which may otherwise occur if the Timeflow package is uninstalled while the sample scripts remain in the project. 
{% endhint %}

{% hint style="info" %}
If you have any custom scripts that rely on Timeflow, compile errors should resolve automatically once the upgrade is complete.
{% endhint %}
