I’ve followed the steps here to migrate the tracker store for Rasa X

> [https://rasa.com/docs/rasa-x/import-conversations/](https://rasa.com/docs/rasa-x/import-conversations/)

my endpoints file looks like this:

> ```
> tracker_store:
> type: redis
> url: <my_redis_url>
> port: 6379
> db: 0
> 
> ```

I tried running the migration tool found here:

> [Migrates a Rasa tracker store (Redis, Mongo, SQL) to Rasa X. · GitHub](https://gist.github.com/wochinge/547a844f9851bb031c129e0416489068)

When I run the script, I get the following error:

> ```
> Start migrating 50 trackers.

Any idea what’s causing this?

Continuing the discussion from [Migrating tracker store](http://forum.rasa.com/t/migrating-tracker-store/10268):

I am getting similar kind of issue as well while migrating redis.

It doesn’t look like the migration tool, or Rasa X support Redis Tracker Stores. I changed my endpoints.yml to point to a mongo instance, and everything works perfectly.
