Upgrade directly to Dremio 15 from Dremio 4.7


Is it possible to directly upgrade Dremio 4.7 to Dremio 15 ?
I believe there are changes in helm chart but are there any other issues to watch out for.

@unni You should be able to upgrade directly from 4.7 to 15, the only thing you need to watch out for is that there are several changes to the planner and the execution engine that you may see some queries have different SQL lans and execution paths
