Load up an SD card with the newest version of debian and give it a spin.
See if everything works as you expect.
If you want to load it on your EMMC do a DD copy of your old image
before you flash
in case you decide to go back.

Yes, but it would be better for you to pose specific questions as you need them answered. Or search the groups here as the questions you’ll have undoubtedly have already been answered many times.
