Hi,
I just wanted to share our experience of upgrading 1.0.10 to 1.2.3.
It happened that first we upgraded both of our two seeds to 1.2.3.
And basically after that old nodes couldn't communicate with new ones
anymore. Cluster was down until we upgraded all nodes to 1.2.3. We
don't have many nodes and that process didn't took long. Yet it
caused outage for ~10 mins.
Here are some logs:
On the new, freshly upgraded seed node (v1.2.3):

----------
I've seen other people reporting similar problem with 1.1.x.
Not sure, but maybe we could avoid this by upgrading seeds last.
Best,
Rustam.
