I'm glad this thread was bumped. I've been putting this off and wanted to make sure this would work as expected and couldn't find an answer in this thread for my exact situation. I'd back up my PS3 again before attempting this but, with regards to activation, I don't think that'd help if I screwed up.
Q1 - With regards to game content: If I deactivate all PS3 systems tied to my account and re-activate them one by one, the first two PS3s get all-access to all games purchased, and systems 3-5 get access to all games purchased before the November 2011 cutoff, right?
Q2 - When a system goes online and sees it's been deactivated, and I re-activate it, I won't have any issues with games not working/requiring re-download/re-installation, correct? It should just understand it's good to go again and won't mess with licenses?
How do you deactivate a PS3? I need to do mine, cos I'm selling it.
To deactivate a single, working PS3 system:
On the XMB menu, go to PlayStation®Network and sign in to your PlayStation®Network account.
Go to Account Management > System Activation > PS3 System.
Select the type of content you no longer want your PS3 system to use.
Highlight [Deactivate System] and press the X button. Your system is now deactivated.
Highlight [OK] and press the X button.
