Help: Can't bulk move items between vaults after department reshuffle

Alright, I'm hitting a wall here and it's genuinely impacting our team's velocity after a big internal re-org. 🚧

We've just restructured our engineering departments, which logically meant moving a ton of service credentials, API keys, and infrastructure secrets from a shared "Legacy-Platform" vault into new, department-specific vaults. I figured this would be a standard bulk operation—check a bunch of items, hit move, select target vault. But 1Password Business doesn't seem to have a native, straightforward way to do this across multiple items at once through the admin console or the desktop app.

I've been poking at the CLI and the API, because that's where I live, but the documentation feels fragmented for this specific bulk use-case. I tried a simple script using the `op` CLI:

```bash
# First, list items in the source vault
op item list --vault "Legacy-Platform" --format json | jq -r '.[].id' > item_ids.txt

# Then, my plan was to loop and move each
while read id; do
# But there's no direct 'op item move' command?
op item get "$id" --vault "Legacy-Platform" --format json > item_data.json
# Then create in new vault and delete from old? Seems messy.
done < item_ids.txt
```

This feels insanely convoluted and risky for something that should be a core admin function. I'm worried about losing item metadata (custom sections, dates) or breaking shared item references.

So my questions for the community:

* Is there a hidden bulk move feature in the web admin that I've completely missed?
* Has anyone built a robust script using the 1Password CLI (`op`) or their REST API to handle this securely?
* If you've done the "export/import dance" via `.1pux` files, did you run into pitfalls with permissions or field fidelity?
* Are there any third-party tools (open-source, preferably) that can manage this kind of large-scale vault reorganization?

I love the platform for its security model, but this operational gap is causing real friction. We're talking about moving hundreds of items, and doing it manually is a non-starter from both a time and error-rate perspective.

Any pipelines or automations you've built around this would be a lifesaver!
