最近有个朋友项目中1830 的AP ,原来是8.2(111.0)版本,为了统一需要升级8.5X 版本,但是升级总是报错、报错、报错:
测试过两种方法:
1. ap-type mobility-express t
ftp://x.x.x.x/ 升级
Starting the ME image download...
It may take a few minutes to finish download.
If it is longer, please abort command, check network connection and try again

2.archive download-sw /reload tftp://
Image downloaded, writing to flash...
do PREDOWNLOAD, part1 is active part
tar: write error: No space left on device
测试过多次都是无法升级,总是报错没有空间,然后翻阅Google查找 ,发现这是一个bug 问题,一股蛋蛋的忧伤:
Upgrade failure from 8.2 mr1 to 8.3 ----- CSCuz81074
描述信息:
Seen upgrade failure for ME Barbados from 8.2 mr1 to 8.3 bec of space issue
已知有bug的版本:
8.2(111.0)
8.3(15.58)
产品:
Cisco Mobility Express
解决办法:
First upgrade the non-ME Barbados to 8.2 MR2 or 8.3 before converting it to ME.

这是一个国外老兄的帖子:
The reason the conversion is not working is because of bug
CSCuz81074.
You will need to upgrade the AP to 8.5.105.0 then you can convert the AP to ME.
To upgrade the AP to 8.5.105.0:
* Download the lightweight image for the AP.
* Upgrade the AP from CLI using the following command: #archive download-sw /reload t
ftp://x.y.z.h/image-name * This will upgrade the AP and reload it.
* Then you can do the conversion.
