validate in interface UpgradeTask

Throws:

getErrors

runOnSpaceImport

public boolean runOnSpaceImport()

This data cleanup task is a nicety that improves the existing data, but the old data wasn't actually wrong, just suboptimal, and is still valid. So this task does not prevent Space Import. It should be fairly simple to adapt it to fix just the data in a single space.

Specified by:

runOnSpaceImport in interface BackupSupport

breaksBackwardCompatibility

public boolean breaksBackwardCompatibility()

This data cleanup task isn't in response to a format change, so doesn't break backward compatibility.

Specified by:
