The following procedure describes how to use NSF migrator efficiently when you need to match large numbers of NSF files to archives that are spread across multiple vault stores:
Add all the NSF files that you plan to migrate, including those that may not have matching archives in the vault store you chose.
Later in the wizard, NSF migrator displays all the NSF files that have not been matched in red. In this list, click the column heading to group all the NSF files with no matching archive.
When NSF migrator asks what you want to do with the NSF files that it migrates successfully, select either the option, or the option.
NSF migrator then hides or deletes the NSF files it has migrated successfully. If your operating system is configured to hide hidden files, they are not visible when you next run NSF migrator. Once you have repeated this process for all your other vault stores, any NSF files that are left are only those for which automatic matching did not work. You can investigate these files individually and select appropriate archives when you run NSF migrator again.
