Well you are probably using trie_version 0 (maybe state_version), with version 1 the value is not attach to the node and only include if accessed by the runtime. WARNING: switching...

There is a link to the md guide and lot of link to different progress on relay chain https://github.com/paritytech/devops/issues/1508#issuecomment-1271565180 . Note that the migration process for parachain may seems more...
