Full copy of cluster

HI .

We have single node cluster with buckets,users,roles etc
We want to copy all data as is to another empty cluster with 3 nodes -3 data,2 index and query
We tried cbbackupmgr and cbbackup .
it looks like I need first to create empty buckets .
copy files as per my understanding will work only if i have 2 identical clusters .

thanks

thanks

@Eddie_Rozenberg you could try making a clone of your single node cluster by copying files and then add other nodes and rebalance cluster.
