## Symptoms

- * MDS import (mds_import.sh) fails on the MDS level with the following error:

  ```
  
  Error:   Failed to upgrade Multi-Domain Server Databases
  Error:   Importing of Multi-Domain Server Databases failed.
  ```

* migrate-YYYY.MM.DD_HH.MM.SS.log shows the following failure errors:

  ```
  
  [DATE TIME] [runShellCommand] Executing command: '/opt/CPmds-R80/bin/upgrade_standby_server -migrate -primaryip x.y.z.w -mdsdb'
  [DATE TIME] [runShellCommand] Execution result: 1, exit code: 5
  [DATE TIME] [DbUpgrader::ExecuteCpdb] ERR: cpdb completed with error code '5'
  [DATE TIME] ...<-- DbUpgrader::ExecuteCpdb
  [DATE TIME] ..<-- DbUpgrader::RunCustomCpdbCommand
  [DATE TIME] [DbUpgrader::exec] ERR: Failed to execute custom upgrade command
  ```

* custom_upgrade_log-YYYY.MM.DD_HH.MM.SS.elg on the Secondary MDS shows the following messages related to full sync: \[DATE TIME\] Succeeded to start full sync from MDS IP x.y.z.w. \[DATE TIME\] Waiting for full sync \[DATE TIME\] Maximum timeout for full sync expired. Exiting... \[DATE TIME\] Full sync has failed for this Multi-Domain Management Server. Please make sure that proper license is installed.
* The cpm.elg\* on the Primary MDS indicates that the sync failed because the Primary MDS could not connect to the Secondary MDS.
* There is network connectivity between the Primary and Secondary MDS servers.
* The clocks on the Primary and Secondary servers are synchronized.

## Cause

Full synchronization with the Primary MDS failed on the Secondary MDS server during the upgrade/import process. The maximum timeout for full sync expired during the import of the database.
