Migrate from vcenter 4.0 to 4.1
Hello Experts,
I want to migrate from vcenter 4.0 to 4.1. In my existing infrastructure, I have vcenter and the database servers running on 32-bit platform. I am looking for the migration path and its requirements.
Many Thanks,

vcenter 4.1 requires 64-bit OS so thats why I am looking for migration path
Whoops, sorry my mistake.
Do you need to complete a migration, rather than install a new fresh server ?

Thanks for your help Andrew. Sorry if I am asking silly questions but I am new to VMWare.
I can definitely leave the performance data but what will happen to my datacenter/cluster/vm and templates/ and network settings. How would these things appear on vcenter 4.1.

Also, the settings for the update manager.

I have the database server that is running windows 2003 enterprise 32-bit and SQL Server 2005 for my existing vcenter 4.0 server. This has got the database for vcenter and the update manager
Can I use my existing SQL server and connect the new vcenter 4.1 to the existing databases so that my new vcenter can look same as the old one without re-configuring anything? Please let me know if this is possible.

Yes, you can.
The easiest method would be to create a new 64 bit server. Create the DSNs to the old database, and then Install vCenter 4.1, and select your old database.
64 bit DSN for vCenter DB
32 bit DSN for VMware Update Manager DB
It will detect and update the database.

OK Thanks.
please confirm if "64 bit DSN for vCenter DB" will work regardless of the SQL server 2005 being installed on 32-bit OS?
If it does, my plan will be:
take backup of existing vcenter and database servers
Switch off vcenter 4.0 server
create DSNs and install vcenter 4.1 and update manager on 64-bit platform using the name and IPs of the old server
After the install my vcenter client will appear same as the old one
If anything fails then use backups to recover the old vcenter and the database.
Please let me know if I have missed any point here.
Again thanks very much for you time and help. Much appreciated.

the setup is very complicated so my target is to avoid re-configuring things on the new vcenter.

It will detect the existing 4.0 installation, and upgrade it, the vCenter Service and Database.
Make sure you have a full backup of the server before you start.
