Source Control Migration Report Messages

The source control Migration Report has an Errors section and a Warnings section. This topic explains the messages that appear in these sections.


The number of actions analyzed versus the number of actions migrated may be different because not all analyzed actions are migrated. Actions that are not migrated include the archive, restore, purge and destroy actions.

If there are errors during analysis or migration, some files or folders were not migrated. The errors do not mean that the migrated database is not usable. You can decide to ignore the files that were not migrated and start to use the migrated sources in Team Foundation version control.

File and folder migration errors are generated when the converter cannot migrate or analyze versions of files or folders because there is an unhandled case in the VSS Converter. This section contains information about the files and folders that were not migrated because the converter could not warn during analysis. Each error message gives a brief description of the error that was found during migration or analysis.

For more information, see Migration Errors.

This section contains information about the loss of information or modification of information because data in Visual SourceSafe cannot be migrated to Team Foundation version control for a known reason. During analysis, the converter warns about this potential loss of information, except for data loss warnings caused by Visual SourceSafe database corruption. When the Visual SourceSafe database is corrupted, you will not be able to retrieve the version through the VSS Explorer or VSS command-line. You can either take some action to prevent the information loss, or you can decide to accept the information loss and run the converter anyway.

Each warning message gives a brief description of the warnings that were found during migration or analysis, and contains a link to a document that contains details about the warning.
