we have plan to upgrade vsphere 4.1 to vsphere 5.1..and
on current vc 4.1, we also have esx 3.5 in diff datacenters , so we are planning to create new vc 5.1 and move only 4.1 stuff form existing to new vc 4.1 to proceed on upgrade
please advice if there is any dependency /prerequisites we have to follow before going ahead?
like database dependency for new vc 4.1..any new db has to be created ? for sso/update manager/new instance to have earlier perf data as well ?
h/w prerequisites to be considered for new vc 5.1
and how can we migrate configuration form vc 4.1 to new vc 5.1..like resource pool/folder/permission?
is there any automated solution like script/utility can be used to avoid any manual error?
or if we have to configure it manully?
