Effect of changing rack id

Hey

I would like to understand what is the effect of changing the rack ids of
the brokers of an existing cluster. Let's say currently the brokers have
rack values "even" and "odd". If I change the rack ids to "rack_1" and
"rack_2" and do a rolling restart will there be any issues in the following
cases:
1. during the rolling restart
2. after the restarts of all brokers is complete

Regards,
Amitav
