If you add partitions, existing partitions' assignment won't change.
Changing the replica assignment subsequently should be fine.

When we first add partitions, will it change the
assignment of replicas for existing partitions?
Nope. It should not touch the existing partitions.
Also, will there be any issues executing the second reassignment
command which will change the assignment again for the new partitions added?
No. 2n
I found this JIRA

Now, we have to use two commands to accomplish the goal - first add
partitions using TopicCommand and then reassign replicas using
ReassignPartitionsCommand. When we first add partitions, will it change the
assignment of replicas
Yes, it seems that we need to fix the tool to support that. It's probably
more intuitive to have TopicCommand just take the replica-assignment (for
the new partitions) when altering a topic. Could you file a jira?
