How to migrate users and keep their IDs unchanged? I'm trying to use migrate_d2d, via the UI, to migrate a site from D6 to D7.  I need to preserve user UID's in the migration.  I'm finding the documentation confusing..

Given this in the UI...



What do I need to do to import the users?
Here is the solution (see image)


Uncheck DNM in 'Option:...' row
Enter 1 as default value
Save
Edit again
A new row will appear for 'Existing user ID'
Select Source field, i.e uid.
Save


This works...
