Doing a little research this morning

I have a copy of L1 The Secret Of Bone Hill, and the Temple of Elemental Evil.

Found two interesting blogs about L1.

I am starting to plan a 5e campaign now, and rather than use the adventure from the starter set, I might try my hand at converting L1, and possible lead to the temple of elemental evil afterwards, seems like a fun idea.

Has anyone ran older modules with new rules?

I've read you need to dial back the treasure, magical items.
