How to post all your existing Instagram posts to TikTok, X, and LinkedIn
Getting your Instagram history onto TikTok, X, and LinkedIn usually means a lot of repetitive copy-paste work — unless you automate it.
With OneUp's crossposting workflow feature, you can automatically send all your existing Instagram posts to TikTok, X, and LinkedIn — 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 X account
- Your LinkedIn profile or company page
Follow the OAuth prompts to authorize each one.
Step 2: Open the Crossposting Menu
- From the top navigation dashboard in OneUp, hover over the dropdown next to Create a post.
- Select Crossposting.
Step 3: Build Your Auto-Post Workflow
- Click Add Workflow.
- Set Instagram as your source account (the platform you're posting from).
- Under content type, choose the post types you want carried over.
- Select TikTok, X, and LinkedIn 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.
