Thank you very much. I couldn't find any definitive answer on that on the
list or stackoverflow.
It's clear that the safest for a prod cluster is rolling version upgrade of
the binary, then the upgradesstables.
I will strongly consider cstar for the upgradesstables

Yes, as the new version can read both the old and the new sstables format.
Restrictions only apply when the cluster is in mixed versions.

But the topology change restrictions are only in place while there are
heterogenous versions in the cluster? All the nodes at the upgraded version
with "degraded" sstables does NOT preclude topology changes or node
replacement/addition?

I also vote for doing all the binary bounces and upgradesstables after the
fact, largely because normal writes/compactions are going to naturally start
upgrading sstables anyway, and there are some hard restrictions on mixed mode

Hi Carl,
the safest way is indeed (as suggested by Jon) to upgrade the whole cluster
as quick as possible, and stop all operations that could generate streaming
until all nodes are using the target version.
That includes repair, topology changes (bootstraps, decommissions) and
rebuilds.
You should
We are about to finally embark on some version upgrades for lots of
clusters, 2.1.x and 2.2.x targetting eventually 3.11.x
I have seen recipes that do the full binary upgrade + upgrade sstables for
1 node before moving forward, while I've seen a 2016 vote by Jon Haddad (a
TLP guy) that backs doing

There's no harm in running it during any upgrade, and I always recommend doing
it just to be in the habit.
My 2 cents.

Hi Pranay,
You only need to upgrade your SSTables when you perform a major Cassandra
version upgrade, so you don't need to run it for upgrading in the 3.x.x
series.
One way to check which storage version your SSTables are using is to look
at the SSTables name. It is structured as:
--.d
When is it necessary to upgrade SSTables ?? For a minor upgrade do we need
to run upgrade stables??
I knew when we are doing a major upgrade we have to run upgrade sstables so
that sstables will be re-written to newer version with additional meta data.
But do we need to run upgrade sstables for u
Check https://github.com/apache/cassandra/blob/trunk/NEWS.txt to see the
steps required, if any, when upgrading.
As a general practice you should also reviw the changes at
https://github.com/apache/cassandra/blob/trunk/CHANGES.txt If upgrading
major versions it is often recommended to be on the la
Is there a tool/guide/document that shows you upgrade paths for different
versions of Cassandra?
For example if you are on version X and want to go to version Y, here are the
intermediate versions you need to upgrade to and here are some special
precautions/Steps you need to take for so and so

Hi,
I have some questions about SSTable compatibility when doing a minor
version upgrade. For example when upgrading from 1.0.3 (Uses version
"hb") to 1.0.6 (uses version "hc").
1. Will I need to upgrade all nodes before performing streaming/repair?
2. Will it be pos
