Does anyone know if it is possible to change factory original sport suspension to comfort suspension just by changing springs and shock absorbers to Audi original part numbers (of comfort suspension) or to after market parts? I assume that alignment/ adjustment of wheels is needed also?

I know usually owners changes to the lower and sportier suspension. I lately bought a used car but later felt that sport suspension is too stiff for my taste.

I should be like you said, but software adjustments/adaptations to more than a few systems should be carried out afterwards with ODIS.

Driving standard or comfort suspension before is a must. Apparently there isn't such a noticeable difference. Try out for yourself.

I have a standard suspension with 17" wheels on and to me the ride can be best described as slightly harsh. Rear end especially.
Don't know how can someone with 19" without adaptive suspension set to comfort manage.
Roads I drive on are decent btw.
 
As El Me says do try one before setting off on an expensive re-fit. I'm going from Comfort on 17" to sport on 19" having had a hire car in the latter set up for a month and much preferred it. To me there was more of a subtle improvement and it's no where near as harsh as, say, a BMW F30 with runflats. Overall the stiffer set up is more to my taste. Less wallowy so family don't get sick and it doesn't float when pressing on like the soft set up does. And I don't drive that fast! Ideally I'd have had 18" wheels for kerb protection but it isn't an option now.
It is telling that Audi no longer offer the wallowy set up as a no cost option on S-Line and above. As well as compromising handling, it did look silly sitting higher with /35 section tyres.

I have now driven the same model with comfort suspension. It wasn't either good compared to my previous BMW F31 with standard suspension. A week ago I went to a local suspension specialist workshop. Based on their and few other recommendations ordered standard springs and Koni Special Actives. The car is going to be 1,5-2,0 cm higher, but for me it is ok as where I live we have long winters and often lot of snow. Koni SA's delivery time is about 6-10 weeks. Long weeks for me.

Long weeks indeed... can't wait to hear your impressions.
How much for the KONI set?
Here in Finland full set (four corners) is about 500€ based on indicative offer. I expect the final price will be little higher.

As you can see from the pic, in some circumstances with the sport suspension the car body looks like diving, specially the rear end. Ski box and trunk are empty, so there is no additional weight pushing the rear down.

I went to workshop on last Tuesday as they emailed that Special Active's has arrived. It was nice surprise as they told me it takes 10 weeks.

My car has 1BE suspension code thus should have 53mm clamping area size at front. Surprisingly when they took the front wheels off and measured the clamping size, they got 49mm which is S-line model (1BV) suspension's size. Little bit confused how this is possible. It also mean that the installation was postponed until early June when new 49mm Special Active's are estimated to arrive.

Looking at the attached photo, your car does look like an sport suspension.
Sorry to hear that.
