Hi wwy0011,
Probabtion periods can consist of different things depending on the organisation.
Usually and at the most basic level it's either nothing or you'll be given a document to sign/keep acknowledging you've successfully completed probation, or just a simple, casual debriefing at the end of the 6 months - that sort of thing.
Some places might do a bit more but really its just a formality for new employees
Wouldn't worry about it, but there's no harm in asking if there's anything they would like you to do.
Hope that's helpful, put some links below with more info
