Planning to upgrade from Hyperion v9.3.1 to Hyperion V11.1.2.1

HI,

I have doubt on upgrade part.

Planning to upgrade from Hyperion v9.3.1 to Hyperion V11.1.2.1

Below products are using in v9.3.1

1. Essbase
2. EIS
3. Web Analyzer
4. Excel Add-in

Below breakup for Hyperion objects
Total number of cubes – 10,
Total number of analyzer reports – 100
Total number of users – 50

 Can we upgrade all essbase cubes from v9 to v11?
 What consideration need to take while EIS upgrade?
 Can we upgrade all 100 reports?
 Can we upgrade all 55 users?
 Any other points need to look while doing upgrade?

welcome your feedback.

Regards
Praveen
