You do not have to use a different PSN ID to play the game just because you moved. Through Sony's license sharing feature for their Playstation console, you can continue to play with your normal PSN ID while still being able to gain the use of DLC purchases through your new PSN ID. With that being said, there are a few things to note. Season Passes granted for a bundle purchase (such as the Deluxe), cannot be license shared, so you'd need to purchase Silver on your Singapore account in order to purchase the Season Passes in-game. If you still have friends or family in Singapore, you can work with them to get wallet codes for your SIngapore-based PSN ID in order to make the Silver purchase on the Playstation store. Alternatively, you can use a website to purchase wallet funds. Unfortunately, as others have said, you cannot transfer your save data from one PSN ID to another PSN ID, so if you wish to continue playing with your current data and be able to play into the future along with the Seasonal content fully available, you'll need to work around purchasing Silver on your account to make the Season Pass purchases or purchase the DLC on that old account. You don't really have any alternatives, since Sony doesn't allow for PSN ID location migration.
