Migration from R7X to R80.10 fails with "mappings that are already mapped in domain" error Technical Level
Symptoms
  • Import fails the $FWDIR/log/cpm_for_cpdb-[DATE].elg file shows:

    uidManager: addMappings(): found 1 mappings that are already mapped in domain:<Domain ID> :
    UID: <R77.30 source object's UID> is already mapped to: <objid of an object already in the R80.10 database>


    (in case of CMA migration, the errors will be in the $MDS_FWDIR/log/cpm.elg file on the MDS level).

    For example:

    uidManager: addMappings(): found 1 mappings that are already mapped in domain:d787f1c9-0c48-9f41-9e91-268e5db308df :
    UID: 97aeb64e-9aea-11d5-bd16-0090272ccb30 is already mapped to: e02fa793-2c05-486a-9dd1-080d514dd4cd
Cause

Multiple objects in the source R77.30 database have the same UID.
