## How to Post All Your Existing Instagram Posts to TikTok, Pinterest, and Discord

Rebuilding your Instagram archive on TikTok, Pinterest, and Discord 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 Instagram posts to TikTok, Pinterest, and Discord — 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 **Instagram** Business or Creator account
- Your **TikTok** account
- Your **Pinterest** account
- Your **Discord** server

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 **Instagram** as your source account (the platform you're posting _from_).
3. Under content type, choose the post types you want carried over.
4. Select **TikTok**, **Pinterest**, and **Discord** as your destination accounts.

> **Platform tip:** TikTok's API only exposes video content, so static-image Instagram posts won't carry over to this 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 TikTok, Pinterest, and Discord accounts stay populated without extra work from you. Learn more at [oneupapp.io](https://www.oneupapp.io/).
