as per documentation the upgrade path for the Community Edition is as follows:
6.0 → 6.5 → 6.6 → 7.0
I do want to do an online update to our existing cluster. Does this mean, that
a) I’ve to update all nodes from 6.0 to 6.5 then all nodes from 6.5 to 6.6. and then all nodes from 6.6 to 7.0
b) I can update the first node from 6.0 to 6.5 then 6.6. then 7.0 and then repeat the same process for all the other nodes
Any help or experience with such an upgrade is highly appreciated.
