Back up the data before you do it. You should have a backup plan anyway, as RAID just isn't enough to keep your data safe. The only way to do that is to have at least one copy on another device.

If I introduce the new drive in addition to the two existing drives, wait for it to sync and then remove one of the original two, what will happen?
Adding a new 4 TB drive will give you an 8 TB volume using RAID-5. Removing any drive after that will result in an 8 TB volume that is degraded (not redundant). Also, the volume would still be non-redundant while the volume is resyncing.
Hot-swapping one of the drives is the best way.
BTW, What size is the new drive? What is the reason for replacing it?
