Switching BetterTouchTool Sync from Dropbox — Any Safe Way to Migrate?

I’ve been using BetterTouchTool with Dropbox (experimental) for syncing, and it’s worked pretty well so far. The thing is, I don’t really use Dropbox anymore and my storage there is running low. I’d like to move my sync setup to something else—ideally iCloud or Google Drive.

A couple of questions:

  • Does the sync feature tend to work better with Dropbox, or is iCloud/Google Drive just as solid?

  • Is there a safe way to migrate my current Dropbox sync folder over without messing up my existing config? I really like my setup and don’t want to risk losing it.

Thanks in advance for any advice or tips!
