[jira] [Updated] (HUDI-6621) Add a downgrade step from 6 to 5 to detect new delete blocks

     [ https://issues.apache.org/jira/browse/HUDI-6621?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ethan Guo updated HUDI-6621:
----------------------------
    Description: In table version 6, we introduce a new delete block format (v3) with Avro serde (HUDI-5760).  For downgrading a table from v6 to v5, we need to check any v3 delete blocks using the new format and ask user to manually restore to a commit before any file slice with a v3 delete block.
