Wanted to get a thread going for informative purposes in case anyone else may be running into this. We previously had BFI setup with a VM Manager in a Central Deployment Type. Post upgrading from 10.0.4.0 to 10.0.5.0 there seems to be an underlying issue/bug that caused the Deployment Type to switch from Central to Distributed. We did notice the below item on the Release Notes
Support for BigFix platform Server Based Computer Groups
BigFix 10.0.4 introduced Server Based Computer Groups which require dedicated support. If BigFix Inventory import was already run with previous version of BigFix Inventory (lower than 10.0.5) then there is a need to resynchronize computer group definition, for details please see documentation.
We attempted the resync as described to no avail. Our VM Manager is still successfully scanning/operating correctly, however we are unable to manage it.
With that said, we currently have a support case with HCL and will keep this thread updates as we progress with that case.
