IfExists - OndraZizka/jboss-migration GitHub Wiki

One cross-cutting concern of all migrators is what to do if some resource already exists in the target server.

Usually, this option is specified in a form conf.<migrator>.ifExists=.... For example:

conf.datasources.ifExists=OVERWRITE

Sometimes, this is more fine-grained, e.g.:

conf.logging.logger.ifExists=SKIP

Possible values are:

• FAIL - the migrator throws an exception and the app fails.
• WARN - the app shows a warning in it's output, and the resource is skipped (not migrated).
• SKIP - the resource is skipped (not migrated).
• MERGE - the resource from the source server is merged into the target server (only where implemented).
• OVERWRITE - the resource from the source server overwrites the one in the target server.
• ASK - the user is asked what to do, in a proper way.
• GUI - the user is asked what to do, using GUI (some kind of dialog).

ASK and GUI are not supported yet.
