  The problem occurs when migrating a DC repository to V8.5.0.
  New baseline types were added in 8.5.0, and existing baselines
  need to initialize their type according to the baseline kind.
  The migration script generate this update for most baseline
  kinds, except temporary baselines.
  Then, if the migrated repository contains some temporary
  baselines, connecting to DC console after the migration will
  failed with the above stack trace.
  

Local fix

• Workaround:
  
  1) Delete the temporary baselines in the original database, drop
  the migrated database and then re-run the migration script
  
  2) Manually fix the migration script, updating the command :
  UPDATE RTSTABLES.Baseline SET type = (SELECT ID FROM
  RTSTABLES.METAMODEL WHERE type = 'brm.Snapshot') WHERE
  baselineKind IN ('Standard') ;
  
  into :
  UPDATE RTSTABLES.Baseline SET type = (SELECT ID FROM
  RTSTABLES.METAMODEL WHERE type = 'brm.Snapshot') WHERE
  baselineKind IN ('Standard', 'Temporary') ;
  
  Drop the migrated database and then re-run the corrected
  migration script
  

Problem summary

• the migration process does not properly handle temporary
  baselines.
  

Problem conclusion

• The code is modified to handle the temporary baselines so that
  no error is detected when migrating a repository
  

Temporary fix
