Solution:
1) Check the version of the jar required for your target
mssql-jdbc-<latest_version>.jar
Note: check the jdk version for your target and oim.
If you are 11g then the jar must be compatible with jdk1.7 but if you are on 12c then it should be working be jdk1.8. same way check the jdk versions on your connector server and target database.

2) Register this jar on oim server using UploadJars utility

3) Give the reference of this jar in setDomainEnv.sh

POST_CLASSPATH="/opt/oracle/apps/OIM_Middleware/oracle_common/modules/thirdparty/mssql-jdbc-9.4.0.jre8.jar${CLASSPATHSEP}${POST_CLASSPATH}"

export POST_CLASSPATH

4) If you have connector server, make sure you have this latest jar enclosed in the bundle on the connector server as well.

Migration of Oracle SOA Suite Composites

Migration of Oracle SOA Suite Composites from 11GR2PS3 to 12C

Follow the below steps:

--> Deploy the jar in 11g version to import in 12C version.

1) Open the SOA project in JDeveloper version 11.1.1.7.0 and create the SAR ( deployable) file into your deploy folder. ( Ex: scaProjectName_rev00*.jar )

2) Close the JDeveloper 11.1.1.7.0 and now open JDeveloper 12c.

3) File -> Import -> select "SOA Archive Into SOA Project" -> OK -> Next -> Composite Archive Browse to the above SAR file created ( Ex: scaProjectName_rev00*.jar )

4) The composite.xml and corresponding BPEL swim lanes will show the content now .

Note: To Deploy the Jar in 11gR2PS3 version we need to install the jDeveloper(11.1.1.7) then SOA extension separately to be installed either via offline file  (download available at OTN or through jDeveloper top menu >> Help >> Check for Updates >> SOA Extension.

unless, 12C Jdeveloper is readily available with QuickStart Installer(download available at https://www.oracle.com/technetwork/middleware/soasuite/downloads/index.html).
