I have been given the task of sorting out an ACS 5.3 server, the devices were all imported from an older 4.x ACS server. All the devices where placed in the 'Migrated_NDGs' group which was created by the migration tool.
Since I have no need for this group is it safe to just delete the group and the devices will remain in ACS?
The only Network Device Groups I really need are the 'Location' and 'Device Type' groups. Sadly I don't have another server to test on and I would hate to delete the group and find out that 700+ devices have also disappeared from ACS!!
Alternatively would it be feasable to export all the device to csv, delete them all from ACS, delete the 'Migrated_NDGs' group and then use the CSV to import the devices back again but minus the 'Migrated_NDGs' group column.
Any help greatly appreciated.
