I think you need to provide more information in the question, what SANs do you have?

iSCSI of Fibre Channel?

could you explain this:-

pls advice for required steps or doc to be followed for this ?

and how to point to existing licence there on 1st vc 4.1 form new vc 4.1?

can we move licence as well to new vc 4.1 for 3.5 environment

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

The docs are simple

Remove ESX 3.5 host from old vCenter and add to new vCenter.

Yes you specify 3.5 license server in vCenter 4.1 configuration.

have to move 3 datcenter for 20 esx 3.5 host running approx 250 Vms now managed by vc 4.1
,also managing esx/esxi 4.1 by same vc4.1

so before we go for upgrade for esxi 4.1,need to move all 3.5 stuff to new vc 4.1 ll only have 3.5

pls advice if any downtime for any of running enviornmnet ?

and how to manage for ressource crunch if any during vc mouvement ?

can we configure new db instance, so that we can also have earalier pef data for those esx 3.5

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

there is no downtime, moving hosts to new vCenter Server.

The VMs are staying in the Hosts, you will have to monitor and manage through vCenter Server.

As for performance data it will be lost, unless you upgrade VC 3.5 to VC 4.1.

there is no vc 3.5,my host already running on vc 4.1 ,its just move form one vc to another vc of same version 4.1

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

okay, just remove hosts and add hosts to other VC 4.1.

you will lose the performance data, you cannot merge VC databases.

Thanks for sharing such good docs here, here my approach is now m running 3.5 and 4.1 on vc 4.1

and trying to move only 4.1 to new vc 4.1, so that all can be easily migrated to 5. 1 direct

No touch to existing vc and 3.5 setup

Please advice best approach for running config of 4.1 only on vc 4.1

how can i proceed with minimal downtime to upgrade start form vc 4.1 to vc 5.1, so that running stuff on this vc will not be affected ?

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

You will need to move all the VMs from 3.5 to 4.1.
