Lars Hofhansl commented on PHOENIX-5607:
----------------------------------------
More brainstorming...
Yet another option is use the phoenix sandbox and include some simple scripts
that download an older client and execute DDL scripts against the sandbox and
compare the output against a set of gold files. That could be done fairly
easily I think.

> Fix For: 4.16.0

>
> Filing this as a blocker for 4.16.0.
> As we've seen with the various failed attempts to release 4.15.0 Phoenix'
> backwards compatibility story is weak, and lacks tests - in fact there're no
> tests.
> We should not allow to ship 4.16.0 without improving that and without tests.
> [~ckulkarni], [~gjacoby] , FYI, what we discussed.
