Hi Kun,

I don't believe the upgrade from CUE 2.2 is supported. You would need to be

at 2.3 as a minimum release version as a first step

Upgading Cisco Unity Express by Performing Software Upgrade

Use this procedure to upgrade to version 7.0:

–From version 2.3.1 and its maintenance versions 2.3.2, 2.3.3, 2.3.4

–From version 3.0.1 and its maintenance versions 3.0.2, 3.0.3, 3.0.4

–From versions 3.1.1 and 3.1.2

–From version 3.2
