Schema changes are not guaranteed to work across versions (especially major
versions where the internode protocol changes) - imagine the new version adds a
new primitive type or collection, adding a new collection on the new version
won’t be interpretable by the old version as anything meaningf
One should avoid doing things (apart from normal traffic) in mixed mode.
The best approach is to upgrade the nodes as fast as possible and then do
other activities.

Thanks for the suggestions.
Few more questions on the mixed mode. Can I perform the below operations on
my cluster in the mixed mode?
1. Add a new datacenter with the new version
2. Remove a datacenter
3. Add more nodes to the upgraded or non-upgraded datacenter
4. Schema changes
I haven't teste
Incredibly slow and has no real benefits beyond a single canary.

Hello,
I am trying to get some suggestions on running upgradesstables(for a major
version upgrade where there is a SSTable format change).
The Cassandra cluster is set up in 3 datacenters with 18 nodes in each
region and here are the 3 options that I am evaluating.
1. Run "nod
