Is it possible to migrate from Schemaless mode to R2 mode?
Yes it is possible, however migrating from schemaless to R2 schema is not easy as each user will need to be migrated to the R2 attributes. This could be done with a powershell script. We recommend our Professional Services team assist if this is being considered.

When switching from Schemaless to R2 in the Control Center this only changes which attributes QAS clients and management tools use. All of the previously-enabled users will suddenly be Unix disabled because the R2 attributes have no values. You can use Powershell to migrate the attributes from Schemaless to R2. There is a –Schema parameter that you can pass to Set-QasUnixUser/Group which will override the configured schema allowing you to copy attributes from one schema configuration to another.
