Creating 2nd ADFS farm in the same domain to be used for dev

We currently have an AD FS 2012 farm setup that it's working fine. We would like to setup a new AD FS 2016 Farm. Can we have two separate ADFS farms in the same Active Directory domain? Would it cause any issues? Should the second farm use different certificates or can we use the same wildcard certificate for the second farm?

We want to make sure the new farm will not cause any issue with the old farm that can cause a production issue.

    You can have as many farm as you want as long as they have different names and identifier it should not be an issue.
    If you are using the Device Registration Service of ADFS (rarely used...), then all farms within the same forest will share the same device registration configuration. If you don't use that feature then you don't care.

    It would also be a good idea to use a different service account to make sure you can manage the farm with no dependency.
