I am upgrading CA SDM from R12.9 to R14.1 as Conventional on Windows 2008 R2 64 bit with MS Sql server 2008. Migration is done but USS is giving prompt that it's not connected to the server. Attach is the screenshot
The issue is mdbadmin user unable to connect to the database. Please work with your DBA to resolve this. The steps from below external URL is for your reference:
java - JDBC connection failed, error: TCP/IP connection to host failed - Stack Overflow
If the issue continues after fixing the issue with the help of DBA, I would suggest you open support issue for further investigation.
