As the rest of our WLCs</P><P>are on 4.1.171.0, I wanted to upgrade these 2 as well. I followed the</P><P>recommendation from Cisco that they first be upgraded to 4.0 before</P><P>installing 4.1. I successfully installed 4.0.206.0 but am now unable</P><P>to delete the version 3.2 image to create space for the new 4.1 image. I</P><P>can't find any command to delete the old file in either CLI or Web</P><P>interface. Any Clues?</P><P>Thanks in advance.</P> Sat, 03 Jul 2021 21:43:46 GMT https://community.cisco.com/t5/wireless/wlc-upgrade-issue/m-p/896926#M49596 colin.lynch 2021-07-03T21:43:46Z Re: WLC Upgrade issue https://community.cisco.com/t5/wireless/wlc-upgrade-issue/m-p/896927#M49598 <HTML><HEAD></HEAD><BODY><P>Hi Colin,</P><P></P><P>You do not need to delete the old file.
