In general, it is good practice to keep the components of ILMT current. Install the latest VM Manager, Scanner, Catalog, PVU table, etc.
The actions running from the supporting Fixlets should also be stopped and replaced with their most recent counterparts. This includes Initiate Software Scan, Upload Software Scan Results, Run Capacity Scans and Upload Results, and Schedule BM Manager Tool Scan Results Upload.
All of the supporting Fixlets have a version number in the name to assist in identifying out of date actions.
