When you move off a previous partner portal, its links do not move with you. They sit in partner emails, in co-marketing pages, in sales decks and in browser bookmarks, and they point at a domain you are about to switch off. This guide keeps them working: you add one redirect rule at your old domain, and Introw catches every incoming link on your new portal domain and sends the visitor to your portal.

​
What you’ll achieve

Every link minted by your old portal lands on your Introw portal home instead of a dead page, with its campaign parameters kept.

​
Before you start

1

Have your Introw custom domain live first

The redirect lands on your Introw portal domain, so connect a custom domain and confirm it serves before you change anything at the old domain. Cutting over in the other order leaves the redirect with nowhere to go.
2

Keep control of the old domain

You need to be able to add a redirect rule at the old hostname, at your CDN or DNS provider. The old portal itself does not need to stay running.

​
Steps

1

Redirect the old domain to /legacy

Add one wildcard rule at your old portal domain that forwards every path, preserving the path and the query string, to /legacy on your Introw domain:
One rule covers the whole domain. There is nothing per-partner and nothing per-link to maintain at your end, and no API key or token to rotate.
2

Check that a link lands

Open one of the old links in a browser. It should end up on your Introw portal rather than an error page. Introw recognises which portal the link belongs to from the domain it arrived on, so there is nothing to set up in Introw.

​
Verify it worked

Follow a real old link end to end, not a hand-typed one. It opens your Introw portal home on your own domain, behind the portal sign-in when the visitor is not signed in yet. Campaign parameters such as utm_source survive the redirect, so reporting on links already in the wild stays intact.

​
Good to know

Every old link lands on the portal home, whatever path it had. A link that used to open a form does not open the matching Introw form, and a partner identifier in the old link is not applied, so share your Introw form links directly where attribution matters. Redirects are not cached, so a partner always follows the current rule rather than a copy a browser or CDN kept.
