Hi Pradeep,
For APM/SDM integration, it is a requirement for both products to share the same MDB.
As they are in separate MDB's now and also in different database management systems, this complicates the situation a bit.
First, you would need to decide on a single database management platform (either SQL Server or Oracle). It would probably be easier to keep the SDM SQL server installation, but that is up to you.
For example, if you keep SDM, then you could install APM 14.1 new against the SAM SDM mdb.
At this point there would likely be some shared contact, location and possibly asset information already in the mdb.
Next, identify and evaluate what DATA and what CUSTOMIZATIONS to port from the old APM to the new APM system.
Then use the APM search extracts to csv in the old APM system, along with the ITAM data importer in the new APM system to import data into the new shared MDB.
For user interface customizations, like configurations, user roles, import definitions, and extended fields, use the APM promotion utility (available at 14.1, C3 and above) to export your customizations from the old to the new APM 14.1, C3+ environment.
See our documentation here on the APM promotion utility: CA APM Environment Promotion - CA Service Management - 14.1 - CA Technologies Documentation
Just my initial thoughts, but that should get you going in the right direction.
