In place upgrades from Rhel 7 to Rhel 8

Greetings!

I'm looking to automate about 1000 boxes from rhel 7 to rhel 8. I'm using rundeck to do it. I'm creating a bash script that will do the preupgrade steps for us.

I'm using this document as a guide:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/upgrading_from_rhel_7_to_rhel_8/index

To do the pre-upgrade script, I need to have to curl the leapp-data file to download a gzip file.

curl -SsL https://access.redhat.com/sites/default/files/attachments/leapp-data-21.tar.gz | sudo tar xzC /etc/leapp

I'm getting an html page from that link, not a gzip file.

The preupgrade script won't work unless the contents of that file is extracted into /etc/leapp/files directory to continue.

Is there a url that will give me a .gz file? I can copy the file to our nfs drive, move it over to /etc/leapp/files directory and extract it there, but getting this working would be preferable

Thanks for your help
