Subject Phoenix 4 to 5 Upgrade Path
Date Wed, 12 Jun 2019 01:02:23 GMT
Hello Phoenix Users List!

We at Box are thinking about the upgrade story from Phoenix 4 to 5. As part
of that, we'd like to understand if these Phoenix versions write data in
formats compatible with each other. In other words, suppose we have an
HBase 1.4 cluster used by Phoenix 4. Can I shut everything down, upgrade
HBase to 2.0 and Phoenix to 5, start everything up again, and expect to
preserve the integrity of the data stored in the original cluster? If not,
is there guidance for what the upgrade process might look like?
