## How to Post All Your Existing Instagram Posts to LinkedIn, Snapchat, and X

Rebuilding your Instagram archive on LinkedIn, Snapchat, and X 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 LinkedIn, Snapchat, and X — 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 **LinkedIn** profile or company page
- Your **Snapchat** account
- Your **X** 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 **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 **LinkedIn**, **Snapchat**, and **X** as your destination accounts.

> **Platform tip:** Content posted to Snapchat through third-party tools lands in Spotlight or Stories depending on your account settings, so check which one applies before running the workflow.

* * *

**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?**

Copying your existing Instagram posts over to LinkedIn, Snapchat, and X manually means opening each post, saving the media, and re-uploading it — repeatedly. You can pause, edit, or expand the workflow later as your destination strategy changes.
