how we can migrate SQL 2014 data to IBM DB2.
One answer
The entry point for the product documentation can be found in the menu item Library above. There is also a link to find interesting articles.
Open the product documentation, select the version you forgot to mention in the question above and type "migrate database" into the search field.
Here is the link for 7.0.2: https://www.ibm.com/support/knowledgecenter/SSYMRC_7.0.2/com.ibm.jazz.install.doc/topics/t_migrate_dbs.html
In the Menu Deployment right to the Library menu you can find links to the Deployment Wiki, which also has a section around upgrade and migration that could provide additional information.
