Migration from Druid 0.9.2 to the last version 0.16

Hello,

I want to migrate Druid from an old 0.9.2 version to the last version 0.16.

My archived datas are stored on a S3 storage; I didn’t find any way to load those archived datas on my new instance.

When I try to load my previous indexDatas on the new unified-console but I get errors (Error message: “Failed to submit task: Instantiation of [simple type, class org.apache.druid.indexing.common.task.IndexTask] value failed: null”).

I made a copy of a subset of my datas to perform the tests (so no risk to crash the prod).

How should I process to deal with that upgrade?

Best regards

Jeremy
