Adding content to a game already on PSM store

Hello

Finally I am about to finish my unity PSM game.
The game is free and I use in app purchase for unlocking further story/game.

Since I have a plan to release more content in the near future that can also be unlocked with in-app purchase for the game, the question is, 'Is there any precautions that I must do for this release to be able to update it with new content later?'
When I finish with the new content, can I just re-upload the new package with the new content?

Thanks for advance, any help is greatly appreciated.

 

Yes you can easily update your game on PSM just the same kind of way Apple, Google, Amazon do.

 

Easy enough, thank you very much.
