Hello,
I have several Dell servers which are running VMWare ESXi 4.1 U1 and U2 (from Dell-customized ISO).
Dell-customized ESXi 4.1 U3 ISO has been released since a long time and the only accompanying doc is "installation (from scratch)". I have been unable to find any official doc from Dell to tell me how to update those 4.1U1 & 4.1U2 to U3 without total reinstall (which means loss of config).
I know how to do generic update using VMware generic ESXi updates which are zip files. But I'm unable to find such zip files for Dell-customized update so I suspect they just don't exist.
I don’t have vCenter, but I have vMA and that's how I did generic update using zip files. If anyone could tell me how to do an update without losing config, I'd appreciate a lot. Thanks.
