Alright, first things first, you need to find and pick the instance of the component you want to tweak. Think of instances as little clones of a master component, scattered all over your design.

Got your instance? Great! Now, head over to the properties panel on the right side of Figma. You'll see a section called "Instance." Click the dropdown next to the instance's name to open up the swap options. Easy peasy.

Now, take a look through the list of components in the swap menu. These are usually from the same set or library. Pick the one you want to replace the original with. The cool part? The new instance will slide right into place without losing its spot or any tweaks you've made.

After you've swapped, double-check that all the properties or overrides you had on the original instance are still good. Sometimes text, colors, or other settings stick around, but it's always a good idea to make sure everything's just right.

Now, if you need to make any more changes, go ahead. Maybe update some text, tweak the colors, or resize things to fit better. Whatever makes your design shine.

If you've got more instances to swap, just rinse and repeat the steps above. Use Figma's tools like group layers and naming conventions to keep everything organized. Trust me, it'll save you a headache later.

Once you're done with all the swaps and tweaks, make sure to save your work. And if you're working with a team, jot down any major changes. It's always good to keep everyone in the loop.
