 ** There are 5 options you can specify CDC client mode from. Take a look at `--help` command output to learn about them.
 
-** You can optionally activate both clusters at CDC client start-up with `--activate-cluster`. You need this for data persistance at source and destination clusters. You can also use `control.sh` capabilities to activate clusters manually.

 NOTE: Start both clusters (as in previous example with Ignite nodes) before starting CDC client.
 
 Here is an example on how to start Active-Passive inter-cluster communication with 2 separate nodes and one thin CDC client for Ignite-to-Ignite replication from cluster 1 to cluster 2 (Run the commands independently):
 ```
 ./cdc-start-up.sh --ignite cluster-1
 ./cdc-start-up.sh --ignite cluster-2
-./cdc-start-up.sh --cdc-client --ignite-to-ignite-thin --activate-cluster cluster-1
+./cdc-start-up.sh --cdc-client --ignite-to-ignite-thin cluster-1
 ```
 
 NOTE: Make sure clusters fully started up before starting CDC client.
