As described earlier, after upgrading from vCenter5.1 to 5.5,vcenter, we also need to upgrade VMware tools for ESXi hosts and VMS, which can be upgraded either interactively or using Updata management two different ways, Here are the steps to upgrade using Updata management:
First, install Updata management
1. Create a dedicated database for Updata management

2.Updata Management requires the use of 32-bit ODBC data sources, 64-bit systems under the C:\Windows\SysWOW64 directory to find ODBCAD32 programs to create a 32-bit data source

3. Modify the default database for the newly created Vum database

4. Test the data source connection

5. Installing the Updata Management program

6. After installation, go to install vsphere Client terminal to open the management plug-in and download Updata management local client to the current PC, Updata Management installation is complete.

Second, upgrade ESXi host
1. Find the Updata management option on the Vcenter home page
650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M01/8D/DC/wKiom1itGyPCbsohAADf66KPa5s460.png "title=" 7.png "Style=" Float:none; "alt=" Wkiom1itgypcbsohaadf66kpa5s460.png "/>
2. In the ESXi Impact tab, select click Import ESXi image and create a base name
650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M01/8D/DA/wKioL1itGySxESlWAADZlE6X-bM631.png "title=" 8.png "Style=" Float:none; "alt=" Wkiol1itgysxeslwaadzle6x-bm631.png "/>
3. On the hosts menu in the Benchmarks and Groups tab, confirm that the image was created successfully

5. Back to Vcenter Home click Host and Cluster options
650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M02/8D/DA/wKioL1itGyTAwEgGAADek5aYq9k130.png "title=" 10. PNG "style=" Float:none; "alt=" Wkiol1itgytaweggaadek5ayq9k130.png "/>
6. The host to be upgraded into maintenance mode, if the virtual machine is located on the shared storage here need to tick check box, if it is on the local disk do not need to tick
650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M00/8D/DC/wKiom1itGyXBJ9HrAAEzYPuhgWw307.png "title=" 11. PNG "style=" Float:none; "alt=" Wkiom1itgyxbj9hraaezypuhgww307.png "/>
7. After the virtual machine migration is complete on the maintenance mode host, click on the additional created baseline in the Updata Management tab
650) this.width=650; "src=" Https://s4.51cto.com/wyfs02/M00/8D/DA/wKioL1itGyWST3YiAAFK9CXil3c918.png "title=" 12. PNG "style=" Float:none; "alt=" Wkiol1itgywst3yiaafk9cxil3c918.png "/>
8. Click Scan, updata Management will compare the current host with the benchmark and click Fix

9. During the repair process, the opportunity display bit has been disconnected, waiting for the repair to verify that the version is correct, exit Maintenance mode, migrate the virtual machine back, and follow this procedure to upgrade the remaining hosts. Upgrade to this host is complete

2. After entering select the Virtual Machine Settings tab, tick the Generate snapshot before repair option to facilitate accidental rollback and customize the snapshot retention time as needed
650) this.width=650; "src=" Https://s1.51cto.com/wyfs02/M00/8D/DA/wKioL1itGyfgFRhwAABgp-TGzqw805.png "title=" 16. PNG "style=" Float:none; "alt=" Wkiol1itgyfgfrhwaabgp-tgzqw805.png "/>

5. Click Scan to compare all the virtual opportunities and benchmarks in the datacenter to see if they are compliant, then click Repair Options, tick the virtual machines that need to be repaired
650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M00/8D/DD/wKiom1itGymT2l-hAAGajHn4Tjs855.png "title=" 19. PNG "style=" Float:none; "alt=" Wkiom1itgymt2l-haagajhn4tjs855.png "/>
7. Select the time of repair in the schedule, which can be fixed immediately, custom repair time, or repair on restart. Note Here : Select Immediate fix, or set up a repair plan, before repair will follow the setup of Step 2 to create a snapshot, so that if there is an unexpected time can be manually rolled back, the fixed virtual opportunity to restart automatically, If the virtual opportunity is not powered on or suspended, it will be restored to its original state after the boot state has been repaired. Upgrading the VMware Tools option on restart does not take effect until the VM restarts, and the snapshot is not created before the repair. Individual can choose according to the actual situation, here with immediate repair as an example
