Upgrade to Easyapache 4 question

I'm trying to upgrade from Easyapache 3 to Easyapache 4. I'm following these instructions here... How to Migrate Between EasyApache 3 and EasyApache 4 - EasyApache 4 - cPanel Documentation

There is a simple instruction:

Migrate from EA3 to EA4
To migrate your server from EA3 to EA4, perform the following steps:

1. Click Migrate. A confirmation message will appear.
2. To confirm that you wish to migrate, click Yes, run EasyApache 4 Migration. The system will start the EA4 migration and display the progress log.
3. Click Done. You can also download the progress log for your records.

Where exactly IS this "migrate" link?

I've tried installing EA4 using SSH command
/scripts/migrate_ea3_to_ea4 --run --install_profile /path/to/profile
and it fails every time.

How exactly do I migrate? All the instructions just send me tail-chasing?

Clearly, I need an idiots guide!?

Any advice gratefully received!

 

Perfect, thank you. All working now.
