Manually downloading every Facebook video or image you have ever published, saving it to your phone, and re-uploading it to Instagram, YouTube Shorts and TikTok is an absolute drain on your time.

With **OneUp’s crossposting workflow feature**, you can set up an automatically post all your existing Facebook posts to Instagram, YouTube, and TikTok and have them drip out over time (so they dont all post at the same time).

**Step 1: Connect Your Social Media Accounts**

Navigate to the **Accounts** page in OneUp. Ensure you have linked:

_Your_\*Facebook\*\* Page

_Your_\*Instagram\*\* Business or Creator account

_Your_\*YouTube\*\* channel

_Your_\*TikTok\*\* account

Follow the quick OAuth prompts to authorize each channel.

**Step 4: Configure Timing & Finalize**
