So far the only older adventures I've modified to run in 5e have been Eberron. I started with The Forgotten Forge from the back of the 3.5 setting book, then proceeded directly to Shadows of the Last War. I was prepping to run the next one, Whispers of the Vampire's Blade, when Real Life intervened and that group more or less disbanded. I injected some Eberron flavor into The Sunless Citadel (the first WotC 3.0 adventure) and ran that for my current group. Its followup, The Forge of Fury, I lost interest in converting while we rotated DMs. (I've run more from both those series, but for different editions/systems.)
I was planning on converting half of Expedition to Castle Ravenloft (the 3.5 adventure), cutting out or handwaving gratuitous combat scenes, some extraneous stuff, and looking to the original I6 Ravenloft for inspiration. (Setting it in Eberron, because that's what I do, following suggestions in EtCR.) It wasn't going to be my turn to DM for a while, so I was mainly just looking to prepare battlemats for the castle, when Curse of Strahd was announced. I would've just used it as a third source to plumb for ideas to put in my mishmash, but one of my players surprised me by buying the book himself and the players wanting to run the whole thing from level 1.
