Why the Migration Progress Is Suspended or Slow?

Symptom

During the migration, the progress bar changes slowly or does not change.

Possible Causes

This problem may be caused by multiple factors, such as the network bandwidth, the number of small files on the source server, and the difference comparison during incremental synchronization.

Procedure

• Check the bandwidths of the source and target servers. Allocate sufficient bandwidth for the migration process without affecting services.
• Check whether there are a large number of small files on the source server. If there are, delete as many unnecessary files as possible.
• During a Linux file-level migration, if the synchronization progress stays at 6% for a long time, please wait patiently. The migration process is comparing and synchronizing the differences between the source and target servers.
• Check the migration status on the SMS console. If it is Connected, wait patiently. If it is Disconnected, see How Do I Restore the Connection Between the Agent and SMS?
