Can I recompile after generating genesisAccounts.json

Hi I am curious if I can recompile after generating genesisAccounts.json using newGenesisAccounts.json with the JPLSnapshot. Do I delete the database -I did -because my genesis account still shows zero

... must I now create my own peers and remove the old database for my balance to show?

The balance is not showing but I recall previously a few years ago I had my one node and it showed the balance from my newGenesisAccounts.json file. Or is my memory incorrect.
