'Cassandra migration from 1.2.9 to 3.11
I need to migrate from Cassandra 1.2.9 to 3.11.
The plan is to go like this: 1.2.9-> 2.0.11 -> 2.2.* -> 3.11
Do you consider that is better to upgrade the cluster or to migrate data from 1.2.9 to 2.2 and after that to 3.11?
Is anything that you can consider a blocker?
I started from those threads:

Migration will require additional hardware also you may not have continuous traffic going for you with migration. Do the upgrades as mentioned in upgrade guides/ instructions. You will do well going upgrade way.
