Hi, until today, in each Elastic project we worked on, we have saved ingested documents into monthly based indices (-%{[YYYY.mm](http://yyyy.mm/)}). We are considering to move from this logical pattern to the one provided by the combination of Index Rollover and ILM technologies, but we have some doubts: 1. Which are the situations in which it is preferable to use the first approach compared to the second and vice versa? 2. Which are the counter-natives for the first approach and vice versa? ---

ILM is just an easier way to manage index management than using date based ones. even if you use date based rollover logic. I think it's safe to say that we recommend using ILM where you can 🙂 ---
