If I have five stacks of corruption on a target and then switch to a different seal, do I still retain the 33% damage bonus on that target for the remainder of the dot or do I have to have SoV up the whole time?

33% damage bonus? Talking about the proc from attacking someone with SoV on them? That proc is based on your seal, not the dot. Changing seals should stop that proc from happening.
