I'm running Temple of Elemental Evil at the office. I also have notes on converting Keep on the Borderlands and the first module in the Slavers series.
Night's Dark Terror is a great choice. I love that module!
IME, the key to adapting older modules is knowing when to add stuff. There are also times when it helps to combine a few separate encounter areas into one fight. I also found that blowing up the map, like assuming each square in some of the caves in KotB are 20 feet across, helps make larger encounter areas with more breathing room.
For instance, in the kobold cave in KotB, I added in some hidden tunnels that the kobolds could use to ambush the party and statted up the chieftain and his guards as higher level kobolds. I also created a backstory to explain why the monsters settled in the caves, the link between the clerics and the monsters, and the reason why the caves were so close to a civilized area without coming under attack (and vice versa). I also made the valley of the caves a little bigger and added some outdoor encounters and sites there.
This image was my main inspiration for a lot of my ideas:
