Launching on a new platform is exciting for about five minutes — right up until you're staring at an empty profile with nothing on it. Whatever content you already have somewhere else doesn't have to sit unused while you start over from scratch.

OneUp's crossposting feature lets you take your existing content from any connected account and push all of it to a brand-new one, so the new account launches with substance instead of silence.

## The problem with starting from zero

New followers judge an account by what's already there. If someone finds your new profile and sees one post, they assume you're either brand new to content creation or not serious about this platform — even if you've been posting elsewhere for years. A populated profile signals credibility before you've said a single new thing.

## How to backfill a new account with OneUp

1. **Connect your existing account (the source) and your new account (the destination)** from the **Accounts** page.
2. **Open the Crossposting menu** from the dropdown next to **Create a post**.
3. **Set your established account as the source**, and your new account as the destination.
4. **Filter by content type** if you only want certain formats (video-only, image-only, or everything) to carry over.
5. **Set the pacing** so your back catalog publishes gradually — over days or weeks — rather than all at once, which can look unnatural to both the platform and to people scrolling your new profile.
6. **Start the workflow.** OneUp works through your existing content and republishes it to the new account automatically.

## What to check before you launch

- Make sure the content actually fits the new platform's format — a caption written for a text-heavy platform might need trimming for somewhere more visual.
- Decide whether you want your whole history transferred or just your best-performing content — OneUp lets you scope the workflow either way.
- This is a one-time migration; once your new account has a foundation, you'd set up a separate ongoing crossposting workflow for content going forward.
