How to FIX: Postman Collection Format v1 is no longer supported

If you are getting this error message when trying to import an older Postman collection, I will show you what to do.

Postman Collection Format v1 is no longer supported and can not be imported directly. You may convert your collection to Format v2 and try importing again.

This error appears when you try to import a Postman collection which used the first version of the Postman collection data format, this is now outdated.

The official way to dealing with this error is to install a Node.js tool called postman-collection-transformer and to use that to transform your collection. However, this implies that you already need to have Node.js installed and be comfortable with the CLI. Some Postman users may not want that. So here is an alternative.

Step 1: Download an older version of Postman

We can get around this limitation by temporarly installing an older version of Postman. For our use-case, the latest Postman v7 will do just fine.
