How can I can use my old Raspbian 8 (Jessie) SD card installation on the Pi 3 B+?
I changed files in
fixup_x.dat) With the files in Raspbian Stretch
/boot and the Pi 3 B+ boots but the USB and Ethernet ports do not work.
EDIT -- I have tested
rpi-update on Raspberry pi 3. After i put SD card on Raspberry pi 3 B+ the USB works but Ethernet and wifi still not work.
EDIT 2 -- After re-installing Raspbian 8 and made
rpi-update on Raspberry pi 3. Ethernet work on Raspberry pi 3 B+ but still wifi not work.
this is dmesg output:

I have tested this solution:
wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb sudo dpkg -i firmware-brcm80211_20161130-3+rpt3_all.deb
I succeeded to compile all my projects in Raspbian stretch, I think it was easier than I expected. I suggest also to migrate to Raspbian stretch.
