CIM instance does not match any known technical system type

Hi Experts,

We have done Technical upgrade of XI 3.0 system to PI 7.3. After upgradation when I go to SLD and Click on business system it will show the Technical system. When I click on Technical system it throw an eorr message

"No details available for system 0000_*****_PRD on arboprd; CIM instance does not match any known technical system type"

I am not able to view the Technical system(TS) details from Business system even though TS exist in SLD.

Please let me know why this error is coming....

Thanks in advance..

Thanks,

Venkatesh
