Unable to set up starrocks

I mounted a volume in a new instance and that volume was having the data of an another starrocks instance. Now, i installed starrocks in my new instance, and while starting the fe node, got below error -

FE saved address not match backend address cached master info: TMasterInfo(network_address=TNetworkAddress(hostname=<previous-instance-ip>, port=9020), cluster_id=<cluster-id>, epoch=2, token=<token>, backend_ip=<previous-instance-ip>, http_port=8030, heartbeat_flags=0, backend_id=11041, min_active_txn_id=6, run_mode=SHARED_NOTHING) received master info: TMasterInfo(network_address=TNetworkAddress(hostname=<previous-instance-ip>, port=9020), cluster_id=<cluster-id>, epoch=2, token=<token>, backend_ip=127.0.0.1, http_port=8030, heartbeat_flags=0, backend_id=11001, min_active_txn_id=6, run_mode=SHARED_NOTHING)

The mounted volume contains IP address of the previous instance which is stopping the fe and be nodes to start.
Is it possible to replace the IP of previous instance to the new one from all the files in this volume or there is no option that to load the data once again ?
Also, how can I get cluster_id and token for the new instance?

No, it not support ip change. You can use FQDN to replace ip when inital startup. FQDN can support changing ip with same hostname.
