hi, i'm testing radius migration. i plan to do it by phase so it will be safer and would have less impact in case something won't turn out right. users will be grouped and thus will be migrated by group. i'm thinking what are available methods/options to do this? i want to have the new radius server replace the old radius server slowly. old radius should still be running when i deploy the new one. AAA of selected group of users will be redirected to the new one. this will be done recursively until all groups of users are served by the new radius server. only after that will i take the old radius server down. can anyone give some more detailed instructions on how this can be achieved? like can i redirect based on user group? thanks a lot. bregards, det
