Transition from Azure classic administrator roles to RBAC roles

I received an email stating: Action required: Transition from Azure classic administrator roles to RBAC roles.

I'm not very familiar with this, so I need very specific guidance. In my research, I saw that if I mess this up, I could get locked out of my Azure account.

I am the only person listed under the "Classic Administrators" tab and I am a Service Administrator.

If found these instructions about doing the transition to RBAC roles and I just want to confirm that they are correct.

To transition from Azure classic administrator roles to RBAC roles, you should remove the Service Administrator role and add yourself as a role assignment with the Owner role at the subscription scope. This will give you the same access as the Service Administrator. To do this, follow these steps:

Sign in to the Azure portal as an Owner of the subscription.

Open Subscriptions and select the subscription.

Click Access control (IAM).

Click the Classic administrators tab.

Add a check mark next to the Service Administrator.

Click Remove.

In the message box that appears, click Yes.

Click the Role assignments tab.

Click Add > Add role assignment.

In the Add role assignment pane, select Owner as the Role.

In the Select field, search for and select your user account.

Click Save.

Can some please confirm that these are correct instructions for my situation?
