## Symptoms

- * "`Failed to import: Failed: null`" error when importing the management database with the "`migrate_server import`" command.

* On the source Management Server, the `$FWDIR/log/cpm.elg` file shows this error during the time when the management database was exported:

  `

## Cause

This file is missing: `$FWDIR/conf/SMC_Files/asm/crc_marker_db.fws`.  
This file stores the Cyclic Redundancy Check (CRC) files for IPS updates.  
The file is generated during each IPS update and is required to be collected during the export procedure.
