In theory, you should not have any problem as long as you select RAID mode in BIOS. The new chipset should be able to handle same RAID 5 volume for storage.
i have good news:
regarding the OS it didnt boot at first, in safe mode i was unable of installing the drivers of the new chipset because windows installer service was arrested, so i managed to boot in VGA mode and from there i could update all the drivers (chipset, lan, audio vga wifi bluetooth...)
regarding the RAID array i set RAID mode in BIOS then everything went ok, windows recognized the datas while it did the rebuilding that lasted a day or two
