Esx 5.0 and vCenter server 5.0 migration queries

Hi All,

We have ESXi 5.0 servers and vCenter servers 5.0 between two locations and the same is configured with linked mode.

My query is,

we have planned to upgrade the vmware from 5.0 to 5.5(both vCenter server and ESXi).

Also SRM enterprise is running with vCenter server 5.0.

how to migrate the SRM from 5.0 to 5.5???

Any best practices??

Please let me know.

Thanks,Manivel
