TarMK Cold Standby - Channel Unregistered for Primary Instance

I'm trying to setup TarMK Cold Standby in AEM6.3.

I can see the log is running in both primary and standby instance.

After the setup done, I still can see assets and sites view from standby instance. Is it expected?

I try to update some assets in the primary instance and those assets are not sync-ed to standby instance.

I also found the status in primary instance is "channel unregistered".

Anyone face this issue before?

Response is highly appreciated.

This issue has been solved by updating the folder structure for config file. Earlier the install folder was renamed to install.primary and install.standby. After create new folder install.primary and install.standby under install folder, the standby is working now.
