Question 1: We are planning to replace Linux servers for our existing Windows servers for FlexNet Manager for Engineering Applications. Can we still be able to continue use SQL database?

Ans: Yes you can use the same SQL database, as long as the only on instance is running. That is either Linux server instance must be running or Windows server instance must be running.

Question 2: We need to move our SQL to a new server, how to configure both admin and reporting to point to database that will reside on new server?

Ans: You can run flexnet site for both admin and reporting module click show advance setting in the configuration then Navigate to page 5 and point the installation to appropriate database server?
