Needed: Guidance on creating a new baseline without converting to Global Configuration Management?

Is there guidance on creating a new baseline without converting to Global Configuration Management?

Ref: The Requirements Management project baselines are archived during the upgrade to gain performance. If after the upgrade you need to access these baselines, you must restore them.

We upgraded this weekend from CLM 5.0.2 to CLM 6.0.1.

We are unable to locate previous project baselines taken in DNG project areas after the upgrade. The baseline interface no longer appears to exist. Our concern is that past baselines were lost in the upgrade migration.

We need e clarification on whether the baselines were migrated to a new location in line with the Global Configuration Baseline functionality or if the baselines, or if we need to investigate a migration error.
