## How to Post All Your Existing TikTok Videos to Instagram, LinkedIn, and Threads

Rebuilding your TikTok archive on Instagram, LinkedIn, 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 TikTok videos to Instagram, LinkedIn, 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 **TikTok** account
- Your **Instagram** Business or Creator account
- Your **LinkedIn** profile or company page
- 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 **TikTok** 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**, **LinkedIn**, 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?**

The workflow runs in the background, so your Instagram, LinkedIn, and Threads accounts stay populated without extra work from you. Get started at [oneupapp.io](https://www.oneupapp.io/).
