So you’ve downloaded all the new VMWare 5.5 goodies and you want to upgrade your vCSA install to v5.5 - this is a little more involved than you may think, however it is very much worth the effort:
In vSphere 5.5, the vCenter Server Appliance limitations have been extremely raised when using the embedded database: Previous to vSphere 5.5, the limits were:
- 5 vSphere Hosts
- 50 Virtual Machines
With vSphere 5.5, the limits are now:
- 400 vSphere Hosts
- 4000 Virtual Machines
Referenced article: http://kb.vmware.com/kb/2057376 Original reports denoted 500 vSphere Hosts and 5000 Virtual Machines.
A tweet Justin King mentioned a 100/3000 limit:
Hot Off the Press! I can confirm the vCenter Appliance 5.5 will support up to 100 hosts and/or 3000 VMs with its embedded vPostgres database— Justin King (@VxJustinKing) September 5, 2013
In short the vCenter Server Appliance now has the horsepower to run in many, if not most vSphere Environments – even in the Fed space.
- Console is now HTML5
- Web Client is now completely platform agnostic - Mac OSX FTW!
- SSO greatly improved
- Recently visited & created objects
- vSphere Inventory Navigator History
- Deploy vCenter Operations from vSphere Web Client
Deploy this to your cluster/host/whatever (with all default settings). (
File -> Deploy OVF Template)
Goto the IP address of your newly deployed vcsa instance and
Accept the EULA, click Next, select Upgrade from previous version.
Copy the key from the new appliance, into the
Upgrade section of the old appliance and click
Import remote key. Copy the upgrade key out of the old appliance and paste it into the
Paste source appliance key section and
Check replace SSL certificates.
Add the password for the new vcsa appliance and continue through all the prompts, view the list of hosts presented by the vcsa appliance and ensure the ones you want that vcsa instance to manage are checked. Make sure you’ve backed up or snapshotted your vcsa instance and continue through the pre-upgrade checker then click
The new appliance shuts down the old appliance and assumes the network identity of the old appliance. If the old appliance was configured to use dynamic addressing, the new appliance will also use dynamic addressing. When the import is complete, the new vCenter Server Appliance starts.
Click close and the vcsa appliance will reboot.
You’re done - your new vcsa appliance has taken the network identity on of the old one and all it’s parameters (you may need to confirm some SSL cert changes for the likes of VUM, vSphere Desktop Client etc).
