Take SFK advantage rating from DEVK to Allianz24?

Hello! Would like to switch from the DEVK to the Allianz24, because it is more than 100€ cheaper for me. However, I was immediately classified in SFK 2 with first insurance of my car on my name at the DEVK, because my parents are insured there and I was over 23 years old as a starter at the beginning of insurance. I now wonder if my SFK4 (from 2007) is also taken over by the Allianz24 at the DEVK. I had also made my driver’s license only at the end of 2004, so that I 2007 actually only two “real” damage-free years can show and not four as with the DEVK (from 2007 SFK4). Or is the Allianz24 enough for the SFK transfer the last invoice of the DEVK with the indication about the SFK? Thank you in advance for your help!
