If you upgrade in place: Stop each node one at a time Swap binaries Start each node Run upgradesstables when all nodes are bounced
If you want to take data from 2.2 and put it into a 3.x cluster, you'll need to run upgradesstables on it offline somehow (like clone that 2.2 cluster/schema and run it offline with 3.x upgradesstables), then sstableloader it into place Note that 3.7 is probably not the version you want - 3.11 is probably much more stable and solves some serious bugs (or 3.0.14 if you don't need features from 3.7 ). The one exception to this would be if you're using a 3.7 lts branch (like instaclustr had at one point - and may still have). -- Jeff Jirsa > On Aug 1, 2017, at 2:24 PM, Harika Vangapelli -T (hvangape - AKRAYA INC at > Cisco) <hvang...@cisco.com> wrote: > > Please help me understand data migration path from 2.2.3 to 3.7. > > 1.
