• Migration on Plesk fails with the error:

  PLESK_ERROR: Error message: Command execution failed on the local server with non-zero exit code.

  rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1651) [Receiver=3.1.2]
  rsync: [Receiver] write error: Broken pipe (32)

• A broken task is created on the source server on every attempt to migrate:

  # plesk sbin pmmcli –get-tasks-list Backup
  error: process ID out of range
  …

Cause

The database with tasks is broken.

Resolution

1. Connect to the source server via SSH

2. Rename the database file:

   # mv /usr/local/psa/PMM/tasks/tasks.db{,.bak}

3. Restart the migration
