How to upgrade OS on pix failover

I have the task of upgradeing a couple of firewall pix 515 sought version OS 5.1 to 6.3 x have failover mode practice a better procedure for this, I have not found one.

Here's what I think:

1. primary secondary stop, let take care

2. upgrade of primary while offline

3 bring primary original online with the new operating system

4. original secondary switch

5 upgrade original secondary while offline

6 bring secondary original online with the new operating system

7. complete

8 go home early

Someone at - it a better plan?

Thanks in advance
