Upgrade guide from 3.4.x to 3.5.x?
Hello
I have been trying to find a guide that describes upgrade process from
3.4.x to 3.5.x.
I cannot find anything on the main zookeeper page.
What i am looking for are breaking changes, configuration changes,
compatibility matrix, is rolling upgrade ok?
Thanks

If you are upgrading a very short lived cluster (no snapshot on server data
directory) you should upgrade to 3.5.7 (not 3.5.6 or less).
There was an important issue in the upgrade procedure that has been fixed
in 3.5.7

Hi Allen
We recently upgrade our Zookeeper clusters from 3.4.13 to 3.5.5.
Yes the rolling upgrade are possible and it is backward compatible meaning zkclient running on version 3.4.13 can still interact with zkserver 3.5.5.
Unless you want to leverage dynamic reconfiguration options , the rest of the configuration are very similar. With new version there are other interesting features like Authentication with Kerberos and TLS , Admin UI which all are optional.
Thanks
