I am trying to follow instructions on downgrading my Jira Server and I am getting an error on import

[Albert Jumaquio]

Following the instructions below

When doing the import itself, using the data, I get this error and could not continue.

Error importing data: java.lang.IllegalArgumentException: [GenericDelegator.makeValue] could not find entity for entityName: UpgradeTaskHistory
