APIC - Controller Stale entry

[aolguin]

Hello,

I am preparing for an Upgrade for APIC and I found that APIC has a controllers under unauthorized controllers.

The SN for this entry is the same as the controller 2

Would it be safe to delete this controller? My concern is that as SN is share with one of the active controllers, by deleting it it cause problems to controller 2

Thanks for your help

@aolguin I'd recommend opening a case with TAC to check before deleting.
