Moving String in a File on the top

Hello,

I have a file containing data and the headers of the data and the headers of the data randomly anywhere in the file but always with the specific string col1;col2;col3

Code:
112233;1133244;112344
112233;1133244;112344
112233;1133244;112344
112233;1133244;112344
Col1;Col2;Col3
112233;1133244;112344
112233;1133244;112344
112233;1133244;112344
112233;1133244;112344

How can I move the headers i.e. Col1;col2;Col3 to the first line of the file.
