Migrating Haystack 3 items
For stations already tagged in Haystack 3, a migration action adds Haystack 4 items that are equivalent to the Haystack 3
versions.
Prerequisites:
- You have an open station connection (local or remote).
- The Haystack 4 tag dictionary is installed.
Perform the following steps:
- To invoke the migration action, under TagDictionaryService, right-click Haystack4 and select .
The Migrate Haystack3 Items window opens.
The migration action accepts a customized namespace. By default the
module://haystack/com/tridium/haystack/data/haystack3MigrationConfig.csvconfiguration file path is selected. You can find the config file under the Haystack module.
If desired, you can make changes to the configuration file. The configuration file consists of the following columns: haystack3 name, type (tag, tagGroup, or relation), optional NEQL query, corresponding h4 name(s), and h4 type (tag, tagGroup, or relation).
- Click OK to execute the migration action.
The migration action kicks off a job that logs the actions taken on each component in the station. Any errors are also logged.
Once you take action to correct these errors, they can re-run the job as required until the migration is complete.
