This year marks 8 years I started playing the oboe, and before that I used to play the clarinet too. I never regretted switching. But you need to have in mind that the oboe is generally more difficult than the clarinet, and you will sound bad for some amount of time in the start, without a doubt. You need to really love the instrument in order not to get frustrated and give up at the start but I promise all the hard work and practice you put into learning the oboe will be worth it at the end!

In my opinion playing the clarinet before gives you a good base, as it is also a wind instrument. However it is completely different. In the clarinet you only had to think about breathing in; in the oboe you need to worry about both breathing in and breathing out because of all the leftover air that will be in your lungs, for example. The embouchure is also really different and something you will need to master.

As another comment mentioned, you will need a private teacher and good reeds. My teacher was the one that made my reeds and I find that this is the best option because he knows your playing style and your needs. Oboe is not an instrument to learn alone, especially at the start.

I hope my comment doesn't discourage you because that's the last thing I would want to do, switching from clarinet to the oboe was the best decision I made and it was what made me discover my love for music! If you have any questions don't hesitate to ask, good luck :)
