It will take lots of prep work and lots of patience...but it can be done. Be sure and...

...Clean all cabinets of grease and grime.

...Sand slightly.

...Take doors and hardware off (number doors & drawers and keep record of where they go back).

...use a good sealer/primer.

...Let each coat dry thoroughly.

...Do not over-paint...that is use too much paint to try to avoid more coats.

...Make sure you use the proper paint and one that is washable.

...Consider sealing them when the pain has dried thoroughly!

If you get in a hurry, you will make a real mess. This may not be a job for a novice painter.

Yes it is possible. I recently painted by black cabinets white. First I gave the cabinets a light sanding with fine grit sandpaper. Then I followed with two coats of primer. I let this dry for two days and followed with 3 coats of Sherwin Williams paint in semi-gloss finish In white.

Yes, it can be done. Comments above are on point. Make sure you number your doors when you remove so that you know where they go back in.

Here’s a compilation of various Hometalk answers about painting cabinets. Some sand and prime prior to painting, one uses a different method. Lots of ideas! https://www.hometalk.com/diy/s-15-different-ways-to-show-off-your-cabinets-for-guests-33337502?page_num=16

Yes you can paint them white. You'll need to prep properly, prime and spray.

Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 120- to 220-grit sandpaper. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water-base, paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.
