Do you still have the old drive? You need to dig out the old config.yaml and look for the following entry:
pool:
logging: *id001
network_overrides: *id002
pool_list:
- authentication_public_key: abc...
launcher_id: '0x2101234...'
Copy that entire section, and replace / add to whatever you have in the new config.yaml file. That section keeps track of your pools.
Every time you make a db backup, don’t forget to also backup your entire .chia and .chia_keys folders.
