What to Expect as a Day 1 at my New Site?

I found out today that I got approved for my site transfer and accepted the offer. My question is for those of you who’ve transferred sites or dealt with those who’ve transferred, what’s the Day 1 like for the “transferees”? Would I report to security and let them know, and they get me set up, or something else? I start at the location the end of this month.
