Since you have only one node, sstableloader is unnecessary. Copy/move
the the data directory back to the right place and restart Cassandra or
run 'nodetool refresh' is sufficient. Do not restore the 'system'
keyspace, but do restore the other system keyspaces, such as
'system_auth' and
Thanks for quick answer.

I understand that, I would like to have all environments with the same

Do you ever intend to add nodes to this single node cluster? If not, I
don't see the number of tokens matter at all.
However, if you really want to change it and don't mind downtime, you
can do this:
1. make a backup of the data
2. completely destroy the node with all data in it
Single node does not make any sense in Cassandra. It should not make any
difference with a single node with whatever number of tokens you start
with. You can change your tokens on the test server and see what happens.

Hi everyone,
I have several development servers with 1 node and num_tokens 256. As
preparation for testing 4.0 I would like to change num_tokens to 16.
Unfortunately I could not add any additional nodes or additional DC, but
I'm fine with downtime. The important part, data should be preserved.
