Can specific volume mappings be selected and/or deselected to migrate in one project? For example, if 5 mappings are mapped in a project, can only three be specified to run in a migration run, leaving the other two out?
The tool is not desiged to select specific mappings within a project to be a part of a migration run, all will be processed.
create a new project with certain volume mappings in it, and migrate them that way. Permissions will still come across as the data migration refers to the database for it's ACL conversions to Windows.
Delete specific volume mappings when they are not needed, then recreate them when it is time to migrate them.
