## How to Post All Your Existing Facebook Posts to Instagram, Snapchat, and Threads

Rebuilding your Facebook archive on Instagram, Snapchat, and Threads from scratch, post by post, adds up to hours you probably don't have.

With [OneUp](https://www.oneupapp.io/)'s crossposting workflow feature, you can automatically send all your existing Facebook posts to Instagram, Snapchat, and Threads — spaced out over time so they don't all publish at once.

* * *

**Step 1: Connect Your Social Media Accounts**

Head to the **Accounts** page in OneUp and make sure you've linked:

- Your **Facebook** Page
- Your **Instagram** Business or Creator account
- Your **Snapchat** account
- Your **Threads** account

Follow the OAuth prompts to authorize each one.

* * *

**Step 2: Open the Crossposting Menu**

1. From the top navigation dashboard in OneUp, hover over the dropdown next to **Create a post**.
2. Select **Crossposting**.

* * *

**Step 3: Build Your Auto-Post Workflow**

1. Click **Add Workflow**.
2. Set **Facebook** as your source account (the platform you're posting _from_).
3. Under content type, choose the post types you want carried over.
4. Select **Instagram**, **Snapchat**, and **Threads** as your destination accounts.

> **Platform tip:** Instagram Business or Creator accounts are required for crossposting — personal accounts can't be used as a source or destination.

* * *

**Step 4: Configure Timing & Finalize**

Choose how much time to leave between each post so they trickle out instead of publishing all at once. Then click **Create Workflow**.

* * *

**Why Use OneUp for Crossposting?**

Once it's set up, your Facebook archive keeps flowing to Instagram, Snapchat, and Threads without you lifting a finger. Try it at [oneupapp.io](https://www.oneupapp.io/).
