What is difference between CUID , OCID and Report ID? When I migrate from one server to another server which IDs will change?

During migration SI_ID might change, CUID's always stay the same.
Not sure what you mean under OCID and Report ID.

There are 3 id's in BI Platform - CUID, SI_ID and GUID.
CUID - unique ID that never changes across environments and clusters.
SI_ID unique ID within single cluster, can/will change when object moves to new system.
GUID - no idea, actually. Not aware how it is being used.
