• InthevSphereCLI,runthevicfg-cfgbackupcommandwiththe-sagtosavethehostcongurationtoa

speciﬁed backup ﬁlename.

~# vicfg-cfgbackup --server <ESXi-host-ip> --portnumber <port_number> --protocol <protocol_type>

--username username --password <password> -s <backup-ﬁlename>

In addition, it’s a good idea to document the host conﬁguration and to have this information available in the

event that problems arise during the host upgrade.

Summary of Upgrade Requirements and Recommendations

The following list provides a summary of the upgrade requirements and recommendations:

• VerifythatyourhardwareissupportedwithESXi5.0byusingthevSphere5.0HardwareCompatibilityList

(HCL) at http://www.vmware.com/resources/compatibility/search.php.

• ConsiderphasingouttheolderserversandrefreshingyourhardwareinconjunctionwithanESXi5.0upgrade.

• Backupyourhostbeforeattemptinganupgrade.TheupgradeprocessmodiestheESX/ESXihost’sboot

disk partition table, preventing automated rollback.

• Verifythatthebootdiskpartitiontablemeetstheupgraderequirements—particularlyregardingthesizeof

the /boot partition and the location of the VMFS partition (the VMFS partition can be preserved only when it

isphysicallylocatedbeyondthe1GBmark—thatis,aftertheESXbootpartition,whichispartition4,andafter

theextendeddiskpartitiononthedisk(8192+1835008sectors).

• UseImageBuilderCLItoaddoptionalthird-partysoftwarecomponents,suchasCIMprovidersanddevice

drivers, to your ESXi 5.0 installation image.

• Movevirtualmachinesonlocalstorageovertosharedstorage,wheretheycanbekepthighlyavailableusing

vMotion and Storage vMotion together with VMware HA and DRS.

• IfthehostwasupgradedfromESXi3.5,watchoutforlopsidedbootbanks.Upgradehostswithlopsidedboot

banks using the ESXi Installer.

• IftheESXiInstallerdoesnotprovideanoptiontoupgrade,verifythattherequireddiskspaceisavailable

(350MB in /boot, 50MB in VMFS).

Upgrading to ESXi 5.0 Using Update Manager

The following section provides an example of using vSphere Update Manager to upgrade an ESX/ESXi 4.x host

to ESXi 5.0.

Requirements

As a reminder, the following requirements must be met to perform an upgrade using Update Manager:

• PerformafullbackupoftheESX/ESXihost.

• Ensurethatyouhave50MBoffreespaceonthebootdiskVMFSdatastore.

• Ensurethatyouhave350MBfreeontheESXhost’s“/boot”partition(ESXonly).

• EnsurethattheVMFSpartitionbeginsbeyondthe1GBmark(startsaftersector1843200).

• EnsurethatthehostwasnotrecentlyupgradedfromESXi3.5(ESXionly).

• UsevMotion/StoragevMotiontomigrateallvirtualmachinesothehost(alternatively,powerthevirtual

machines down).
