Can You Transfer a Black Ops 2 Season Pass from PS3 to Xbox?

No, you cannot transfer the Call of Duty: Black Ops II Season Pass from PlayStation 3 to Xbox 360.

Digital licenses are strictly tied to the platform ecosystem where they were purchased (PlayStation Network vs. Xbox Live). There is no cross-platform entitlement system for DLC or Season Passes from that generation.

Your Options:

• Repurchase on Xbox: You must buy the Season Pass again on the Xbox 360 Marketplace to access the DLC maps (Revolution, Uprising, Vengeance, Apocalypse) on that console.
• Check for Cross-Buy (Rare): Occasionally publishers offer "Cross-Buy" promotions, but this was not available for Black Ops II Season Pass content.

Note: This applies to the Xbox 360 version. Modern Call of Duty titles on current-gen consoles sometimes support cross-progression for battle passes, but not for legacy Season Passes.
