Lightbulb [Q] Updating from ICS 4.0.4 to Jellybean 4.3

I was wondering If it is safe to flash a 4.3 stock Firmware via odin on my I9300 4.0.4 device.It's baseband version is I9300XXLH1 which hasn't recieved any OTA updates so I'm going to flash one via odin.And I also wanted to know if any fullwipes will be needed after flashing new firmware cause for my I9500 which I flashed a 4.3 firmware on a 4.2 one I needed a fullwipe in order to fully boot the device...
