Migration options for custom vertex id.
We are planning to use custom vertex id. I have huge data set that is already ingested with default vertex id and now I wanted to use custom vertex id. Any suggestion how can I migrate from default vertex id to custom vertex id ?

custom vertex id (String) feature to avoid duplicate vertex
I have a graph(Backed with Cassandra and read/write consistency QUORUM) which will have Vertex property "recordId" and "type".
I have disable consistency locking on property say "recordId" in my graph, I see duplicate vertex getting created for same "recordId", due to concurrent writes.
Note - In above case we were not providing any custom vertex id, but relying in Janusgraph to generate vertex id.
Now, I'm using custom vertex id (String) feature to maintain consistency of vertex in my graph, where I say recordId=custom vertex id.
Questions -
If I use "recordId" as custom vertex id, I'm hoping that there will be no duplicate vertex created in graph with onsistency locking on property say "recordId". Is this fare understanding ?

How does remote gremlin server reacts to credential rotation.
I have are remote gremlin server setup with backend database as Cassandra. I need to rotate Cassandra Username/password once a week.
My Cassandra credential are stored in gremlin server properties file and are injected by side-car container at boot time.
How does the Janus graph reacts to if Cassandra credential are changed ?
How can I achieved a rotation of Cassandra credentials without any downtime for gremlin server?
