Hello,
I have issue with migrate from version 8.19.2 to 9.0.6
On version 8.19.2 from Stack Management/Upgrade assistant I migrated system indices
Next I founded some critical old indexes - deleted them,
And during upgrade I’m receiving below error on stack:

Basically I don’t know what to do with this issue, but founded:
> Caused by: org.elasticsearch.xcontent.XContentParseException: [-1:22093] [data\_stream] unknown field [failure\_rollover\_on\_write]
I don’t know with what data stream it is related.

I believe this is caused by an out of order release upgrade path. I believe any 8.19.x will need to be upgraded to 9.1.x.
I know this is probably a little confusing and has to do with 8.19.x being released at the same time as 9.0.x.
