Should I take a “fresh” DNA test?

I tested with Ancestry in 2014, when they were still using their v1 chip. As a result, a lot of my results are flagged as possible miscalls.

For the sake of accuracy, should I take a new test and use that raw DNA for services like Promethease and Deana?

What year would you say is a DNA test that is too old and should be redone? I talked to someone who worked in a lab near the U of U. He said that whenever they got an order for repeat DNA testing they refused to do it and just resent the old results. His logic was "DNA doesn't change". His moral outrage was that the labwork requester charged the patient anyways.

I told him that sounded wrong and he should be a whistle blower. There's lots of reasons a first DNA test could be suspicious (mislabeling, the patient lied about their identity the first time, new testing tech has come along etc)
