For information I have found a post [cardano-node/install.md at master · input-output-hk/cardano-node · GitHub](https://github.com/input-output-hk/cardano-node/blob/master/doc/getting-started/install.md) and i have followed these instructions. I hope it will work. I will update shortly if this has solved the issue. Thx ---

I have tried what is explained here > ![image](https://us1.discourse-cdn.com/flex023/uploads/cardano/original/3X/e/d/ed20dd6f7b1da90fce38da746a4bb50bb3ec52eb.png) and I have been able to compile. Now my node is in starting state. I will see if it works properly in a moment. ![image](https://us1.discourse-cdn.com/flex023/uploads/cardano/original/3X/a/4/a4e5e50b038b0d794cf969867faf854a6d92a77d.png) The question I have is should I do this (the libsodium and reinstall of cabal and ghc, etc ) also on other relay and producer ? or can I simply copy the carano-node & cardano-cli binaries ? Thanks in advance for your help. ---

Theoretically should work but being a new major change I don’t know if other changes are required… (config file, etc) but u can try… rename bin folder (bin\_bkp) and copy the new bin folder ---

Thanks for your reply. I will see the best path to take here. I have not decided yet. For information I have notice a changes in the config file \> [Cardano Configurations](https://hydra.iohk.io/build/13695229/download/1/index.html) If I am not mistaken the following one was not part of my previous config files. “TraceAcceptPolicy”: true, I do not know since then this update occurs in the config file as I haven’t updated these files since last major HardFork ---

I wanted to provide a quick update. I have been able to upgrade my relay A. I have copied the binaries to my second relay and I had the same issue the binaries can be executed because of the libsecp256k1. So the following cmd have to be executed: ![image](https://us1.discourse-cdn.com/flex023/uploads/cardano/original/3X/6/0/6031552f8bde5f5ab4d515f6a99d080344acebe3.png) instruction are provided here \> [cardano-node/install.md at master · input-output-hk/cardano-node · GitHub](https://github.com/input-output-hk/cardano-node/blob/master/doc/getting-started/install.md) Once done I was able to run the binaries and now my second relay is starting so all fine. I will perform the same on my producer and it should be fine. As usual Thanks to this community that is always willing to support and help others.

Installing libsecp256k1 and increase from 12 GB to 16 GB minimum memory seem to be the only new requirements for building and running Cardano Node 1.35.0 when upgrading from 1.34.1 CHG
