Hi Teresita,
Please go through the below blog,
New solman uses CRM_UI for ITSM and change request management.

1. 5. Support of SLFN transaction types in Solman 7.1, transition from SLFN to SMIN
There is no migration from former SLFN documents to SMIN documents, as the new SAP ITSM functions are only available in the SAP WebClient with new business object types.
The former Incident Management scenario, SLFN documents, can still be used after an upgrade to the next SAP Solution Manager release. SAP recommends a transition phase, as shown in the figure below.
Existing support messages (SLFN) should be processed in the Work Center or SAP GUI, until they are completed.
See note 1613908 Old Transaction Types in SAP Solution Manager 7.1
There is no support for using crmd_order or the old message documents in 7.1. The note states that existing documents can be finished but if you continue creating new ones with the old transaction types you will not get any support.
