Migrate 1,000 Links Without Losing Analytics History

The scariest part of switching URL shorteners isn't the switch itself — it's the fear that every link you've published, and every click you've measured, will vanish. That fear is usually misplaced. With the right order, you can move to a new platform and keep both your live links and your historical analytics.

This guide gives you a repeatable migration: export, recreate, re-point, verify — without breaking anything.

The two things you must preserve

A migration has two independent goals:

1. Keep every published link working. The short codes people already clicked must still resolve.
2. Keep your click history. The analytics you've accumulated shouldn't reset.

Most "lost data" horror stories come from confusing these two. If you re-point the domain but don't recreate the codes, links 404. If you recreate codes but don't carry over history, your reports start from zero.

Step 1: Export everything

Before touching anything, export the complete link list with all fields:

• short_code
• original_url (destination)
• title, created_at
• clicks (the count)
• click event history if available (dates, referrers, devices)

Export as CSV. This is your source of truth. If the platform doesn't offer an export, build it from the API (most shorteners have a GET /links endpoint you can page through).

Step 2: Recreate codes identically

On the new platform, recreate every link keeping the exact same short code. The goal is that the published short URL — e.g. https://short.com/ab3x7 — resolves to the same destination as before.

Two ways:

• Import via CSV/bulk API if the new platform supports it.
• Create programmatically with the new platform's API, setting customAlias to the old code.

The key constraint: the code must be identical so existing published links keep working. If a code can't be reused (e.g. reserved), create a redirect from the old code to the new one instead.

Step 3: Preserve historical analytics

Export the click history and import it as historical data on the new platform. Some platforms let you seed a starting click count or import event history; if not, record the historical counts separately so your reports reflect reality.

Do not delete the old platform during the transition. Keep it live for the overlap so that:

• Any link you haven't migrated yet still resolves.
• You have a backup source of the full history.

Only retire the old platform once you've verified everything migrated and the new platform is handling traffic.

Step 4: Re-point and verify

Once codes exist on the new platform, re-point traffic:

• If you control the domain, update the DNS/redirect so the short domain serves from the new platform.
• If you're changing the whole short domain, publish a redirect map from old to new (301s), so old links still work and pass equity.

Then verify:

• Spot-check a sample of codes return the correct 302 to the right destination.
• Confirm the destination URLs are intact.
• Check that new clicks are being recorded.

The order that prevents breakage

1. Export full link data + history.
2. Recreate codes (identical) on the new platform.
3. Import historical analytics.
4. Re-point DNS/redirects.
5. Verify a sample.
6. Keep old platform live during overlap.
7. Retire old platform only after confirmation.

Common mistakes

• Re-pointing before recreating codes → mass 404s.
• Changing codes during migration → published links break and history fragments.
• Deleting the old platform too early → no fallback if something's missing.
• Not importing history → reports reset to zero.

The takeaway

Migrating a shortener doesn't have to lose anything. Export everything, recreate the exact same codes, import your history, re-point, verify, and keep the old platform alive during overlap. Follow that order and your 1,000 links keep working and your analytics keep their context.

The two things you must not lose

A link migration has two assets that must survive: the live links (so nothing already published breaks) and the analytics history (so your reporting does not reset to zero). Losing either defeats the purpose of migrating. The live-link requirement is met by preserving slugs or setting up 301 forwarding so old URLs keep resolving. The history requirement is met by exporting the historical click data before you move and importing it into the new platform where supported, so your dashboards and year-over-year comparisons continue seamlessly. Planning for both up front is the difference between a migration and a data reset.

Preserving the links themselves

The click path is the first thing to protect. When you re-create links in the new system, keep the existing short codes so URLs already in emails, bios, print, and QR codes still work. For anything you cannot reuse verbatim, put a 301 in place from the old address to the new one — the redirect preserves the link's function and carries whatever link equity the old URL has accumulated. The 301 is also what lets you move the underlying domain without breaking every previously shared URL, which is the same protection the Bitly migration playbook relies on.

Preserving and validating the analytics

The analytics are where migrations usually silently lose value. Export the click history before the move, map it to the new links, and verify after the import that the totals transfer — not just "something imported," but that the numbers actually match the source. Watch for caveats that can corrupt the transfer: history exported on a reporting delay, links with multiple aliases whose data must be merged, and timezone differences between platforms. Validating a sample after import catches these before you discover, months later, that a whole segment of history is missing.

Running the migration as a reversible operation

A history-preserving migration should feel reversible, not like a one-way leap. Stage it: import and verify in parallel with the old system, switch a low-risk subset first, confirm links resolve and history is present, then complete the cutover while keeping the old domain alive for a transition window. Keeping a clean export of the source data as a backstop means you can re-import or audit at any time. Handled this way, the migration protects both your live links and your history, and the risk of data loss drops to near zero.
