While attempting to migrate a System Center Configuration Manager 2007 driver package to System Center 2012 Configuration Manager, the action fails and the following error is shown in the migmctrl.log file:
SCCM Provider is missing read, write, or delete privilege for the driver package source path
This can occur if the Configuration Manager Provider system has insufficient permissions on the driver package source path (NTFS and/or Share permissions).
Grant the System Center 2012 Configuration Manager Provider system full control permissions on the driver package source path.
During migration, the error above is only shown for Driver packages because Migration Manager needs to process some content in the source path, so it will fail during the migration itself. If you migrate a regular software package, it will succeed no matter whether the destination site has access to the source path or not, but later, SMS_DISTRIBUTION_MANAGER (distmgr.log) which starts up to process this package, will fail due to insufficient permissions on the package source path.
