Hello, I am running 0.90.2 cluster and I want to upgrade it to 0.90.10.
I created a new instance with 0.90.10 and I expected it would join to the
legacy cluster but with the following error, it couldn't join. The new
instance doesn't have any data and I was expecting newly joined instance
would copy the replica from the old one.

java.io.IOException: Expected handle header, got [17]]
I guess 'Expected handle header' error usually occurs when mixed versions
of ES are used but is this normal procedure of rolling upgrade of
elasticsearch?
Thank you
Best, Jae
