upgrade path

Pre upgrade Steps

1-Deploy some vms
2-Create some snapshots
3-create some compute offerings

FOLLOW UPGRADE STEPS DEFINE IN RELEASE DOC

Post upgrade steps

4-upgrade existing vms with compute offering (before upgrade)
5-Deploy a vm and Create new compute offering
6-upgrade existing vms with compute offering (created after upgrade)
7-Upgrade  new vm  using olde compute offering
8-upgrade new vm using new compute offering
(REPEAT FOR EACH SSVM,CPVM,VR,RVR)
9-upgeade ssvm with old offering
10-upgrade ssvm with new compute offering

1-upgrade should go properly
2-step 4 should fail
3-step 5 should be successful
4-step 6 should fail
5-step 7 should be successful
6-step 8 should be successful
7-step 9 should be successful

Change SO of a stop VM

1-Stop vm
2-change SO

step 2 should be successful 

Restore VM

1- Scale up CPU/RAM
2-destroy vm
3-restore VM

1-Restore VM should boot using last  used service offering by vm.

Dashboard

scale up cpu /RAM

1-Change CO of a running VM

Dashboard should display new value of CPU and RAM according to CO values.
