Dear A,
Many thanks friend for the help and support.
Once i try to download zip file "upgrade-from-esx3.5-3.5.0_update05-207095.zip" over there it is mentioned the following.
what does it mean "This package requires the esxupdate utility" , do i need to download "esxupdate" utility to upgrade esx3.5ga release to esx3.5 U5. or it's included in the package.
regards
Mr VMware.
