[SUPPORT] 0.11 hudi upgraded to 1.0.

[liujinhui1994]

I read the official information and can't seem to find out how to upgrade lower versions of hudi to 1.0. We currently have 7,000 hudi tables in version 0.11. Can you guide me? I'm worried about the big risks.

hudi 0.11
spark3.2
flink1.8

you may need to upgrade to 0.15.0 first, we better do some manual tests from 0.15.0 to 1.0

@liujinhui1994 To migrate to 1.0.0, you have to atleast upgrade to 0.14.x +. There is one known regression also when you migrate from 0.11.0 to 0.14.1 and 0.15.0 regarding ComplexKeyGenerator. Please check it out if this will affect your usecase or not.

flink 1.8?

As far as I can remember, flink 1.8 is not supported in version 0.11.
