How can we start the solo chain with existing chain data?

Question

I am not able to start the chain. Is there any way to start the chain with existing database.

you can add --base-path /path/to/database flag when starting the chain. if you are doing --dev I think your database will be in the /tmp which will be deleted every new start. — Yeou, Sep 26 at 1:21

For that first we need to export the state of the chain on any given blocknumber.

./target/release/chain-node export-state --chain=currentChainSpecRaw.json --base-path /Users/pcs/documents/node01 1000 > chain-exported-100.json

Then you need to start the the chain with the exported chainspec.
