JR4 to JR6 Export and Import
Installation and Configuration
Quote: The help "?" in the import module says to make a comma delimited list of the users by ID number...
The "?" help (your screenshot) refers to Quota IDs, not User IDs so what I described above is still correct.
The quota IDs of your JR4 site may not be the same as the equivilent quota IDs in your JR6 site so this form is where you can 'map' them, so just enter the ID of the JR4 quota next to each JR6 quota as in this case, there is no need for commas and multiple quotas.
Hope that makes sense
