Our office has a CTX100
Actu3a Cpu
slot 101 - BWDKU1
Slot 102 - ADKU1
Slot 103 - Incoming Lines
Slot 104 - IES/16

My question is, can I remove the ADKU1, and replace it with another BWDKU1? we have plenty of licenses, just need more physical extentions.
Trying to avoid adding an expansion cabinet right now.
