Background - Two site v4 u2 vsphere environment.
SRM is used to protect the production site.
Prod site has 3 ESX host servers.
DR site has 3 ESXi host servers.
There are two physical vCenter servers using Windows 2003 32b and SQL 2005 express.
SQL 2005 express is loaded on the vCenter servers.
2005 SQL express needs to be upgraded to full SQL Server. We have exceeded SQL express's capacity.
The hardware is on the v5 compatibility list.
Here is the upgrade path I am considering.
1. P2V both physical vCenter servers; PROD_SERVER & DR_SERVER.
2. Ensure vCenter & SRM is stable on the virutal consoles before continuing.
3. Use the vmware procedure for doing an inplace SQL server upgrade on virtual vCenter servers.
4. Ensure vCenter & SRM is stable before continuing.
5. Rebuild physical PROD_SERVER & DR_SERVER.
a. OS – Windows 2008 R2 64b
b. Add 32 GB RAM
c. SQL 2008 R2 Standard 64b
6. Install vCenter, Update Manager and SRM on physical consoles.
7. Install ESXi 5 u1 on esx hosts
8. Upgrade VM hardware and VM tools on all VM
What do you think of the P2V of the physical vCenter servers? The virtual vCenter servers are temporary and will be used a "bridge" for the upgrade..
Our prod_cluster has outgrown SQL express. My thought is to do an inplace upgrade on the virutal vCenter servers. This way we can snapshot to rollback the upgrade, if needed.
