After upgrading from 7.7.18 to 8.15.1 I DO NOT see nodes folder

Hello,
Hoping some one can help solve me this puzzle, I was previously on ES-7.7.18 and I just upgraded to 8.15.1 but as opposed to ES-7.7.18 I do not see nodes folder created in ES-8.15.1 and Instead all I see is a nodes file created which has this written in it " written by Elasticsearch 8.15.1 to prevent a downgrade to a version prior to v8.0.0 which would result in data loss"

I am confused why nodes folder is not created in ES-8.15.1
Below are components of /data folder
0 -rw-r-----. 1 elastic elastic 0 Sep 9 19:24 node.lock
4 -rw-r-----. 1 elastic elastic 115 Sep 9 19:24 nodes
0 drwxr-x---. 2 elastic elastic 42 Sep 21 17:37 snapshot_cache
4 drwxr-x---. 20 elastic elastic 4096 Sep 21 17:57 indices
8 drwxr-x---. 2 elastic elastic 4096 Sep 21 19:16 _state

Below are my settings in elasticsearch.yml file

cluster.name: mysearchCluster
discovery.seed_hosts: ["IP-OF-MY-ELASTIC-SERVER"]
xpack.security.enabled: false

am I MISSING SOMETHING ? Any help will be appreciated

That's the expected behaviour since 8.0.0.
