public interface BackupSupport

Interface implemented by AbstractUpgradeTasks which provide information to the backup manager to manage backward and forward compatibility. If you're unsure how to fill this information, please have a look at https://pug.jira.com/wiki/display/CONFDEV/How+to+add+to+or+change+the+Confluence+Database Also, please list your upgrade task in https://pug.jira.com/wiki/display/CONFDEV/List+of+upgrade+tasks+in+Confluence


Method Summary
 boolean breaksBackwardCompatibility()
          Returns true if a new export can't be imported in an older instance.
 boolean runOnSpaceImport()
          Returns true if an older Space can't be imported in a new instance without running this task.
 

Method Detail

runOnSpaceImport

boolean runOnSpaceImport()
Returns true if an older Space can't be imported in a new instance without running this task. For example:

Note that tasks don't run on space import yet, so we just reject the import in this case.

Since:
5.2

breaksBackwardCompatibility

boolean breaksBackwardCompatibility()
Returns true if a new export can't be imported in an older instance. Breaking compatibility means a snapshot of the new version will not work at all with the previous version. For example: The best way to test is whether a newer export can be imported (with fully working features) in an older instance.

Since:
5.2
