Barovia shares the same type of system that was introduced for advancing the campaign, without the patrols each week and with a significant change to the hunting system, making it MUCH easier. The other two are your standard 'complete the related dungeon, complete the campaign', which will require you fill your weekly haul in a similar manner to Chult and Omu, and advance through the campaign tasks.
There are 7 new achievements associated with Barovia, and 4 of them can be achieved relatively quickly all on your own, with the hunts related one being much easier with a solid group of guild mates or friends. The achievements in this campaign are significantly easier to receive. If you've already gone through the farming annoyance to complete all the hunts in Chult and Omu, then breathe easy.
