Description:
When you import a .csx file which was exported out from BC 6.0.1, 6.0.2  with an HF1 environment into another BC 6.1.0 or 6.0.2 environments, we observe that not all the participants are getting imported.

Symptoms:
When logging into the Administrator after importing a .csx that was previously exported out from bc 6.0.1 or bc 6.0.2 (including HF1), all participants are not imported. No exceptions are found in the log files.

Cause:
This is not an issue with the import but an issue with the export from the BC 6.0.2 environment. The issue is the participants with null values for guidelines (guidelines not being available during export) were not exported properly. When reviewing the export logs,  these type of strings indicate the issue.
