Recently I have upgrade my Environment form 4.1 to 5.1...
Please advice..best way to upgrade VMFS 3.58(came form 4.1) to VMFS 5(5.1)..
Can We Upgrade VMFS 3 to 5 and then Increase Data Store Size form 2TB..to get all features ..which we get with newly created VMFS 5 Data Store ?
Can we Simply upgrade existing VMF3 to 5 with existing size <2 TB.. ?
Or If we have to Create newly Fresh Data store?
Do we have limitation for LUN/Data Store/VMDK size in 5.1. ? as earlier it was allowing Max 2 TB LUN.
Will there be any Risk /down time required by going any of the ways ?
Actually here we are having issue due to less number of lun id free, as earlier we had Data store/Lun size max 2 TB ,So Can we increase Lun Size now ?
Will there be any dependency with SAN/Hardware ?
