How to change Fat AP to Fit AP module ?

Execute the following commands in user view：<H3C>ap-mode fit，Use command <H3C>del /un xxxx.bin  to completely delete the fat AP version in flash. After you delete the AP version，you need to upload the Fit AP to AP.The version name must be consistent with the Fit AP version name stored in the AC flash. If you use the manual registration method, the AP without a version can download the version from the AC after registration (if there is a Fit AP version on the AC). However, if you use the automatic registration method , an AP without a version cannot download the version from the AC by itself. You must manually upload the thin AP version of the AP to successfully register.
