In the release notes of vma 4.1 (http://www.vmware.com/support/developer/vima/vma41/vma_41_relnotes.html) it seems possible to update the appliance from 4.0 to 4.1 using vima-update:
Important: You can use the vima-update vima-update
update VIMA 4.0 to vMA 4.1 GA. You cannot, however, use the
utility to upgrade VIMA 1.0 to vMA 4.1.
I've tried with "sudo /usr/sbin/vima-update scan" but it found nothing, same for "sudo /usr/sbin/vima-update update", it return:
Skipping bulletin VIMA400-200911002, it is installed or obsoleted
Skipping bulletin VIMA400-200906001, it is installed or obsoleted
Skipping bulletin VIMA400-201002201, it is installed or obsoleted
Nothing to update.
I've searched on the documentation but did not found anything related to update/upgrade with vima-update..
Anyone know how to do it?
