Why am I unable to upgrade Aruba 3200 Mobility Controller to ArubaOS version 6.2.x.x
This article applies to Aruba 3200 Mobility Controllers.
Software enhancements and new features added in ArubaOS 6.2 require extra memory and Aruba 3200 Controller with default memory of 512 MB is getting low on free memory. Therefore, Aruba has released a field kit (3200-MEM-UG) where you can upgrade the memory of 3200 controller to 1 GB.
ArubaOS 6.2.x is supported only on the newer MIPS controllers (7200 Series, M3, 3400, 3600, 600 Series,3200XM, and any 3200 with its memory upgraded using 3200-MEM-UG kit). Non upgraded 3200 will not be supported for ArubaOS 6.2.
Also the legacy PPC controllers (200, 800, 2400, SC1 and SC2) and 3200 (default memory) are not supported. DO NOT upgrade to 6.2.x if your deployments contain a mix of MIPS and PPC controllers in a master-local setup.
