Skype for Business – Move-CsRgsConfiguration : Object reference not set to an instance of an object.
During a side-by-side Lync 2013 to Skype for Business migration I encountered an error moving Response Groups using Move-CsRgsConfiguration. Move-CsRgsConfiguration -Source lyncfepool.domain.local -Destination skypefepool.domain.local This resulted in the error “Move-CsRgsConfiguration : Object reference not set to an instance of an object.”. To resolve I ran Move-CsRgsConfiguration again with the -verbose switch: Move-CsRgsConfiguration -Source lyncfepool.domain.local -Destination skypefepool.domain.local -verbose Verbose output below: VERBOSE: Performing the operation "Move-CsRgsConfiguration" on target "service:ApplicationServer:skypefepool.domain.local/531286fe-e965-4c1c-9949-26eca4d8d3db".
