Thanks for ideas!
I've found that some backrefs in obj_uuid_table to 'instance_ip' are duplicated
with strange backrefs to 'instance-ip':
obj_uuid_table:d4f5b4c5-50ab-4989-a131-c6288125c616,backref:instance_ip:094be277-eac2-4e50-88ed-c689c6c39f73,{is_weakref:
false, attr: null}
obj_uuid_table:d4f5b4c5-50ab-4989-a131-c6288125c616,backref:instance-ip:094be277-eac2-4e50-88ed-c689c6c39f73,{is_weakref:
false, attr: null}
After removal of backrefs with 'instance-ip', the database has been imported
successfully.
Now trying to find where in the code such backrefs can appear.
