## Symptoms

- * "migrate export" fails when the pre-upgrade verifier is called.  

* Errors in the migrate log /opt/CPshrd-R/log/migrate-DDD_MMM__D_HH-MM-SS_YYYY.log shows:  
  `[ExecCommandGetOutput] ERR: Command completed with error code -1`  
  `[PreupgradeVerifierRunner::exec] ERR: Preupgrade verifier had failed`  

* This happened after reverting to an R75 snapshot and then trying to run the R75.40 'migrate_export' tool.

## Cause

Corrupted registry `$CPDIR/registry/HKLM_registry.data`.

The value for *:CurrentMSP* in the registry has been changed to something other than 0, 1, 5, 6 or 7 depending on the currently installed version on the server.

This causes the migrate_export to attempt to execute the pre-upgrade verifier with the following command parameters set:

*./pre_upgrade_verifier -p /opt/CPsuite-R75.40/fw1 -c 6.0.2.xxx -t 6.0.2.5* where xxx equals the corrupted string.
