IBM Bigfix and IBM Inventory Database version


We have Remote Database for Bigfix running on SQL 2008R2 . and Same with IBM Inventory SQL 2008R2.

We are migrating Bigfix DB from SQL 2008R2 to 2012.

My question:
Do we have any compatibility issues to connect IBM Inventory DB (SQL 2008R2) to IBM Bigfix DB (SQL2012) ?

Yes, You can migrate your Bigfix DB from 2008 to 2012. Just follow migration steps provided by IBM.
