How does Elements Connect values migration work?

The migration process runs asynchronously and in multiple stages.

1. Creation of Elements Connect custom fields in Jira Cloud

2. Migration of Elements Connect field values

Created Connected custom fields will only be partially preconfigured.
These fields will need to be configured in Step 3.

On the Data Center side

1 - Field mapping

If a Jira project containing Elements Connect fields has been migrated during this JCMA migration, send Elements Connect custom field format to Jira Cloud for custom field creation.

2 - Field values migration

For each selected project:

• Field values are sent to Cloud

• Data is transmitted in batches of 1,000 issues

• Once all batches are sent, the DC side of the migration is complete

On the Cloud side

For each value:

• The app updates the Cloud field using the Jira Cloud API

Because Jira Cloud enforces API rate limits:

• Some update calls may be temporarily rejected

• Rejected updates are automatically placed in a queue

• The system retries them until successful

This ensures all values are eventually migrated.
