Issue Summary

Space migration using CCMA 3.4.2 and 3.4.1 is failing with the below error.

INFO [pool-66-thread-31] [agent.service.execution.PlanExecutionService] info Step fb5f1b0a-7e30-4213-8302-8bf0edc0bee7 completed execution b55261ce-5b33-4cf4-9ae0-2f79cb1a2f42 with result=StepResult(isSuccess=false, isStopped=false, message=Import to cloud failed. Message: ERROR: column "fieldid" of relation "temp_import_label" does not exist, result=null, e=null)
ERROR [pool-66-thread-31] [agent.service.stepexecutor.ProgressTracker] error Step failed, message: Import to cloud failed. Message: ERROR: column "fieldid" of relation "temp_import_label" does not exist

This is reproducible on Data Center:

Steps to Reproduce

1. Install CCMA 3.4.1 or 3.4.2 on a confluence. The issue is observed with the Postgres database. The default export method is CSV.
2. Try to create a migration plan with more than 80 spaces.
3. Some of the spaces fail with the errors highlighted below.

Expected Results

Migration should be successful.

Actual Results

The below exception is thrown in the xxxxxxx.log file:

ERROR [pool-66-thread-31] [agent.service.stepexecutor.ProgressTracker] error Step failed, message: Import to cloud failed. Message: ERROR: column "fieldid" of relation "temp_import_label" does not exist

Workaround

• Disable csv export
  • For PostgreSQL, add dark feature migration-assistant.enable.original-xml-export
  • For other database implementations, remove dark feature migration-assistant.enable.new-space-export
• Rollback to version without csv export, e.g. CCMA v3.3.13
