Add Level to pro site


What do I do if I want to add a Level to prosite.

Let say I have 3 Levels, 1. Starter 2. Pro 3.Extra

I want to add level Mini between 1 and 2.

What do I have to do?

I thought about:

1 Delete levels Extra

2 Delete Level Pro

3 Add Level Mini

4 Add Level Pro

5 Add Level Extra

6. Update on wp_pro_sites level 3 to Level 4

7 Update on wp_pro_sites level 2 to Level 3/

Is that correct? Any better way to do this?
