We are planning to upgrade our clusters from DSE 6.7 to DSE 6.8. Currently, we have two DCs with 6.7 and we are wondering will it be okay to add another DC with DSE version 6.8.
High level steps that we are planning to follow.....
1) Add a new DC-X with 6.8
2) Remove one of the old DC-A (6.7)
3) Add another new DC-Y with 6.8
4) Remove another old DC-B (6.7)
Please let us know your thoughts on what is the best way to follow to upgrade quick and safe way.
