Every new platform comes with the same problem: you need content to post, and you need it fast, ideally without spending the next month creating everything from scratch. If you're already active somewhere else, the fastest content library you can build isn't a new one — it's the one you already have.
OneUp's crossposting feature turns your existing content on any connected platform into an instant library for a new one, without you writing, filming, or designing a single new post.
Why "create less, migrate more" works
Most creators and brands underestimate how much usable content they already have sitting on an existing platform. A year of Instagram posts is also a year of potential LinkedIn posts, X threads, or Pinterest Pins — the content already exists, it just hasn't been formatted for the new destination yet, and OneUp handles that transfer automatically.
How to build a content library from existing posts
- Connect your source account (where your content already lives) and your destination account (the new platform) from the Accounts page in OneUp.
- Open the Crossposting menu from the dropdown next to Create a post.
- Set your source and destination accounts for the workflow.
- Filter by content type or performance — you can bring over everything, or scope it down to just your strongest-performing posts if you'd rather build a smaller, higher-quality library first.
- Set your pacing, spacing posts out so the new platform fills in gradually rather than all in one day.
- Launch the workflow, and OneUp automatically republishes your existing content to the new destination on schedule.
Where this works best
This approach is most useful when you're expanding to a platform that shares a content format with your existing one — video-heavy platforms crossposting to other video-heavy platforms, or image-based accounts moving into another visual platform. The closer the format match, the less manual cleanup you'll need afterward.
