Knowledge Base

Migration tools tried to perform operation in 3 attempts: [Error 3] The system cannot find the path specified:

 
backup restore migrationdatabasedebugplesk for windowsplesk migration

Symptoms

  • Plesk migration fails with an error similar to this one:

    Migration tools tried to perform operation in 3 attempts:
    [Error 3] The system cannot find the path specified: 'C:Inetpubvhostsexample.comhttpdocswordpress20170217unusedbefore-upgrade-to-3.8wp-contentcachepage_enhancedwww.example.net200910some-long-string-with-alot-of-symbols-in-it-with-some-timestamp/*.*'

  • This is logged to %plesk_dir%varmodulespanel-migratorsessions<MIGRATION_TIMESTAMP>debug.log:

Cause

The error is caused by a long path (>255 symbols). It's a known bug, PMT-3684, which will be fixed in future Plesk updates.

Resolution

The error occurs when Plesk Migrator attempts to fix connection strings and obsolete paths in *.config files. As a workaround:

  • Connect to the source server via RDP and shorten the path, or
  • After migration, connect to the target server via RDP and fix any connection strings/obsolete paths in the .config files if necessary.
