Introduction

It sounds strange and it's kind of controversial way of supporting the FIM product, but uninstalling FIM properly is part of the FIM administrators job too.

There might be various reasons to remove the product from your environment.

  • after a merger, the product is migrated to another FIM installation on another network
  • only particular and limited functionality is used (and more specifically served by another product)
  •  functionality is phased out, installed functions are not used anymore
  •  (feel free to add more scenarios in here)

Whatever the reason, you should do it properly and thoroughly.

What are the things you should think about?

It's not as simple as just reversing the installation procedure, you need to make sure all security components are reset/reconfigured and removed from the systems.
