I have a potentially simple question about the wiring in my separated garage after I upgraded the feeder wire from my main distribution panel. The garage was previously grandfathered in without a ground. I am replacing a ton of concrete between the house and garage and its the last time i can access that area. (plus the old wire was just put down on the ground and the old concrete path was poured over it, doubt that was proper…. it didn't survive the concrete demo). I ran a new proper three wire with ground.
The question I have is, do I simply separate the bare grounds and neutrals to their individual bars? Is it that easy in the subpanel after everything else is done, or could there be more complicated changes that im not processing by separating these. ie. need to upgrade garage plug and light circuits as well. Should everything still work the same once i separate them..? I am absolutely overthinking this! Thanks!

In addition to separating and isolating the neutral from ground you also need to drive a ground rod(s) (some jurisdictions will require 2 even though it is an accessory ground) and bond any other metal piping system in the garage.
