Change of insurance Huk-Coburg/Huk24 Kilometer?

Hi At the moment I have insured my Golf4 with the Huk-Coburg, but will possibly change over to the Huk24 in the next few months because this is almost 100 Euro a year cheaper. However, I have the problem that I have exceeded the indicated kilometers (9000) by a good 15,000. If I now want to re-insure myself with the Huk24 I did not have to enter the current mileage anywhere. If this is then asked by the Huk-Coburg (and then punishes a possible contractual penalty) or do I just have to state it later? Don’t get me wrong I would raise the kilometers (if I don’t change the insurance) at the Huk-Coburg anyway, but then I can of course drive much less next year to get back to a normal mileage. Then it would of course be quite right to be able to start “from the front” again with an insurance change. Mfg, Heinrich
