Procedure to upgrade ILMT to BigFix Inventory

Hi All,

We have an existing environment with BigFix Platform and ILMT (0$ purchase and limited to IBM publisher) which is configured in a single server. Now we are planning to use BigFix Inventory (BFI) which will help to discover software inventory from multiple publishers.

Now my question is BFI is from HCL and it is not a 0$ purchase. What is the procedure to configure BFI with existing license file which we already used for BigFix with ILMT. Do we have an option to upgrade existing license file from HCL?
