-- The migration process creates a temporary pod that uses `rsync` to copy data from the source PVC to the target PVC.
-- Logs of the migration are stored in `/tmp/target/rsync.log` within the target PVC.
-- After the migration, verify the data integrity and delete the temporary pod if necessary.
+- The migration process creates a temporary pod that uses parallelized `rsync` to copy data from the source PVC to the target PVC.
+- You can control the number of parallel threads and CPU resources via the `THREADS` and `CPU_REQUEST` options.
+- After the migration, verify the data integrity and delete the temporary pod.
