I am currently running a vCD 1.5 environment which I need to upgrade to 5.1 but want to make sure I have a way back should I encounter any issues with my environment afterwards.
I have an idea on how to achieve this and wanted to run it past the community for feedback.
The steps I'm thinking of taking are:
1) Stop all activity on the vCloud cells
2) Backup the vCloud SQL database
3) Take a VMware snapshot of the vCloud director Cells
4) Take a VMware snapshot of the vShield Manager
5) Run the vCloud upgrade and also upgrade the SQL database
6) Run the vShield Upgrade
7) Test the environment
If things don't go as planned, my roll back approach is as follows:
1) Stop all vCloud cells
2) Restore SQL database
3) Revert to snapshot on vCloud Cells
4) Revert to snapshot on vShield Manager
Do I need to do anything else?
Should I worry about the resource vCenter server or the hosts attached to the vCloud Cells? Do the ESXi agents get updated?
