Migrate cassandra between two DCs

Hi, all

We have several nodes in DC1 and DC2 and we want to move all nodes in DC2 to
a new DC3, also IPs will be changed. The whole progress will last about 1-2
days.

Can we simply stop all nodes in DC2, move to DC3, chage IP config in
storage-conf.xml then start all nodes in DC3?
Or shall we do REMOVE TOKEN before moving and do BOOTSTRAP  after moving?
Or any other suggestions?

Thanks!
albert_e

This will work if you upgrade to 0.6.3 first.
