You have to be close enough to the center to get there in a specified time frame because lungs don't last long after they're removed from the donor. You also have to have a place to stay very close to the hospital where the surgery was done, usually for at least three months and a caregiver who will do everything required. Those requirements are generally deal breakers.
The answer to your question is "it depends". I wish I could be more definitive, but the answer depends on a lot of different things; some you can control and some you can't. With a TX, you do trade in one set of problems for another. Pre TX you can't breathe properly, get really sob, use O2 and take lots of meds.
Post TX, your immune system will be really compromised and is probably the weakest link: if something goes wrong there, it's often hard to fix. You would really have to be careful with something tike the corona virus. You'll be taking anywhere from a dozen to 30 meds every day, probably for the rest of your life, all having to do with keeping your immune system under control. A number of the meds and even the procedure can have side effects. You're still subject to anything that comes along, like cancer, diabetes and anything else you might develop with or without COPD.
How long it takes to recover from the surgery depends on your condition prior to surgery. If you were in good shape, it'll take less time; if you were really deconditioned, it'll take a lot longer. I have one friend who left the TX center after a month because he was in such good shape; I have another friend who was finally discharged from the hospital after five months. Part of it depends on what they find when they do the TX and how straightforward the surgery is. My friend who left so quickly had a very easy surgery where everything went absolutely the way it was supposed to; my other friend had one where everything that could go wrong did.
On the plus side, breathing should be a lot easier, understanding that is NOT a guarantee. Under ordinary circumstances, it should be near normal with new lungs, but things do go wrong and you need to understand that.
Do you have to relocate there theyy trird to tell me that you do
