Please extract ten key words from the passage: The bug comes from an internal ticket.

Our internal customer create system replication with below way:
We clone the storage volumes of the primary site, attach them to new hosts, run new register_rename no start and then register this site as a secondary of the initial one. This is all an online operation without downtime.

But after with the new feature from bug 298738. The register_rename operation is failed with error in "hdbrename.log".

The root reason seems command "hdbnsutil -convertTopology ... --test" needs to be executed when source DB on old hosts is offline. 


I attached the installation package in the bug's directory.


Could you please check if the command could be done when source DB is online?
