Are save files going to be the same as they are for BL2?

I’m buying BL3 in a few days, but like most people here, I own every game in the series on steam, and when it’s available there, I’m going to buy it again so I can continue playing with friends that aren’t buying it until it’s available there. My question is whether or not I’ll be able to transfer my save and if the save files are going to be the same as they are for BL2.

You don’t need to buy it again if you want to play with friends on Steam.

I’m only buying it on the epic store out of necessity. I’m switching over to steam as soon as possible because it’s a better platform. I just want to know about the file system.
